It’s a language feature that seems pretty powerful… But I rarely use dynamic or anonymous objects, preferring strongly typed classes in 99.999% of cases. A C# tuple is a data structure that has a specific number and sequence of elements. Contents. Which one looks best do you? Create tuples to store immutable data. This code example shows how to create a C# Tuple and use it in a C# application. For example : If we use the new construct of Tuples (Named or Unamed), you are able to set values on the resulting tuple object. A tuple is an object capable to hold a collection of elements. But something that sits right in the middle is Tuples. Tuples are objects that pack elements of -possibly- different types together in a single object, just like pair objects do for pairs of elements, but generalized for any number of elements. Queue Main Menu 1.Insert 2.Remove 3.Display Others to exit Enter Your Choice : 4 ----- (program exited with code: 0) C Queue Programs Simple Queue Program in C Programming dot net perls . Mit diesen Operatoren werden Member des linken Operanden gemäß der Reihenfolge der Tupelelemente mit den entsprechenden Membern des rechten Operanden verglichen. An n-tuple is defined inductively using the construction of an ordered pair. Other arithmetic operations do not apply on Tuples. Den Standardnamen eines Felds können Sie immer verwenden. A predicate is also a delegate like Func and Action. Documentation of the various operations and the stages a queue passes through as elements are inserted or deleted. 2. make_tuple() :- make_tuple() is used to assign tuple with values. 2. make_tuple() :- make_tuple() is used to assign tuple with values. For example, a single record with UserId, FirstName, LastName, Salary and so on can be called a tuple. At compile time, the compiler replaces non-default field names with the corresponding default names. You can create 3-tuple using Tuple(T1, T2, T3) constructor. Snow, on the mountaintop, gives way to dirt and grass. In simple terms, you can define a tuple as a single record of various types of data. Your email address will not be sold or shared with anyone else. A queue is a collection that stores the values in FIFO style (First In First Out). And yet, Tuples drew me in…. Let’s look at some alternatives to how we might return the same data from a method. So you might have heard the name “ValueTuple” thrown about, but what is that exactly? Queue is an abstract data type which can be implemented as a linear or circular list. So here we have it. The functions fst and snd (reference tuples only) return the first and second elements of a tuple, respectively. C# Queue with Examples; Linked List Implementation in C#; C# | Tuple. You can have a quick refresher on what made it in here : https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-7. Zur Kompilierzeit ersetzt der Compiler die nicht dem Standard entsprechenden Felder durch die jeweiligen Standardnamen.At compile time, the compiler replaces non-default field names with the corresponding default names. A quick note on the immutability on Tuples. The main difference being that the Tuple class, being a class, is a reference type while Value Tuple (Which we will talk about below) is a value type (struct). This code demonstrates the two ways of creating tuples as first introduced by C#. In those cases you either explicitly specify the name of a field or access a field by its default name. I recently had to write interview questions specifically for features that made it into C# 7. Both tuples have the same number of elements. Die Namen von Tupelfeldern werden ignoriert und nicht zugewiesen. Indexing. This class itself does not represent a tuple, but it provides static methods that are used to create an instance of the tuple type. Der Name einer Variablen wird in den folgenden Fällen nicht auf einen Tupelfeldnamen projiziert:The name of a variable isn't projected onto a tuple field name in the following cases: In diesen Fällen geben Sie entweder explizit den Namen eines Felds an oder greifen über den Standardnamen auf ein Feld zu.In those cases you either explicitly specify the name of a field or access a field by its default name. Dies gilt auch, wenn ein Feldname explizit angegeben oder abgeleitet wird (wie im folgenden Beispiel):You can always use the default name of a field, even when a field name is specified explicitly or inferred, as the following example shows: Bei der Tupelzuweisung und bei Vergleichen der Tupelgleichheit werden Feldnamen nicht berücksichtigt.Tuple assignment and tuple equality comparisons don't take field names into account. In this Java tuple tutorial, we will learn about Java Tuple – a generic data structure and how we can use tuples in a Java program. Tuples, by default, are not present in Java programming language as a data structure so we will use one nice third-party library javatuples for it.. Table of Contents 1.What is tuple 2. In .NET 4.0 (e.g. Like people waiting to buy tickets in a queue - the first one to stand in the queue, gets the ticket first and gets to leave the queue first. Normalerweise verwenden Sie Tupel, um lose zusammengehörende Datenelemente zu gruppieren.Typically, you use tuples to group loosely related data elements. Es gibt die folgenden Hauptunterschiede:The main differences are as follows: Weitere Informationen finden Sie in den folgenden Hinweisen zu Featurevorschlägen:For more information, see the following feature proposal notes: Im folgenden Beispiel wird veranschaulicht, wie Sie eine Tupelvariable deklarieren, initialisieren und dafür auf die zugehörigen Datenmember zugreifen können: The following example shows how you can declare a tuple variable, initialize it, and access its data members: Wie im obigen Beispiel zu sehen ist, geben Sie zum Definieren eines Tupeltyps die Typen aller Datenmember und optional die, As the preceding example shows, to define a tuple type, you specify types of all its data members and, optionally, the. So the first change in C# 7 is that you can now used named tuples. let third (_, _, c) = c Generally, it is better to use pattern matching to access individual tuple elements. But in most cases, the usage of a Tuple is going to be wrong. .NET 4.0 introduced a set of very interesting new data structures, called tuples. Member functions (constructor) constructs a new ... A, name: Lisa Simpson ID: 1, GPA: 2.9, grade: C, name: Milhouse Van Houten ID: 2, GPA: 1.7, grade: D, name: Ralph Wiggum Defect reports. Concatenation of tuple is the process of joining of two or more Tuples. Review all nodes using breadth first search starting from root node at level 0. Required fields are marked *. Die Namen von Tupelfeldern werden ignoriert und nicht zugewiesen. Dies wird im folgenden Beispiel veranschaulicht:The names of tuple fields are ignored and not assigned, as the following example shows: Sie können auch den Zuweisungsoperator = verwenden, um eine Tupelinstanz in separate Variablen zu dekonstruieren .You can also use the assignment operator = to deconstruct a tuple instance in separate variables. C# unterstützt die Zuweisung zwischen Tupeltypen, die die beiden folgenden Bedingungen erfüllen:C# supports assignment between tuple types that satisfy both of the following conditions: Die Werte von Tupelelementen werden gemäß der Reihenfolge der Tupelelemente zugewiesen.Tuple element values are assigned following the order of tuple elements. Für das Feature „Tupel“ werden der Typ System.ValueTuple und die zugehörigen generischen Typen (z. B. System.ValueTuple) benötigt. A quick crash course in Tuples (aka, What I learned about Tuples in the past week). (double, int) t1 = (4.5, 3); Console.WriteLine ($"Tuple with elements {t1.Item1} and {t1.Item2}. Weitere Informationen finden Sie unter Auswählen zwischen anonymen Typen und Tupeltypen.For more information, see Choosing between anonymous and tuple types. Personally I prefer the out method when I have a conditional result. So we do away with that whole Item1, Item2 business. Beim Namen des Kandidaten handelt es sich um das Duplikat des expliziten oder impliziten Feldnamens eines anderen Tupels. for each tuple position, the type of the right-hand tuple element is the same as or implicitly convertible to the type of the corresponding left-hand tuple element. Dequeue (Double Ended Queue) 1. A tuple has multiple fields of different types. Dies bedeutet, dass eine Operation sofort angehalten wird, wenn ein Paar mit ungleichen Elementen erkannt oder das Ende von Tupeln erreicht wird. In the simplest programming terms, a tupleis a data structure that contains an ordered sequence of types. Dies gilt auch, wenn ein Feldname explizit angegeben oder abgeleitet wird (wie im folgenden Beispiel): You can always use the default name of a field, even when a field name is specified explicitly or inferred, as the following example shows: Zur Kompilierzeit ersetzt der Compiler die nicht dem Standard entsprechenden Felder durch die jeweiligen Standardnamen. A scan down the list reveals some interesting stuff (out variables, pattern matching, throw expressions, discards), and also some stuff that I honestly don’t seem to ever use (local functions – I honestly don’t see the use of these…). Tuples in Java 3. Dies wird im folgenden Beispiel veranschaulicht: You can explicitly specify the names of tuple fields either in a tuple initialization expression or in the definition of a tuple type, as the following example shows: Ab C# 7.1 gilt Folgendes: Wenn Sie keinen Feldnamen angeben, wird er ggf. Hier ein Beispiel dazu: Wie an diesem Beispiel zu sehen, ist die Verwendung etwas umständlich. Hierfür können Sie eine der folgenden Vorgehensweisen wählen:You can do that in one of the following ways: Explizites Deklarieren des Typs jeder Variablen in Klammern:Explicitly declare the type of each variable inside parentheses: Verwenden des Schlüsselworts var außerhalb der Klammern, um implizit typisierte Variablen zu deklarieren und die Typen vom Compiler ableiten zu lassen:Use the var keyword outside the parentheses to declare implicitly typed variables and let the compiler infer their types: Verwenden von vorhandenen Variablen:Use existing variables: Weitere Informationen zur Dekonstruktion von Tupeln und anderen Typen finden Sie unter Dekonstruieren von Tupeln und anderen Typen.For more information about deconstruction of tuples and other types, see Deconstructing tuples and other types. There are four types of Queue: 1. Leave a comment if you used Tuples in this initial framework version and what the use case was, because I am genuinely curious who used them like this. Wie im obigen Beispiel zu sehen ist, werden Tupelfeldnamen bei Operationen mit. That is, an operation stops as soon as it meets a pair of non equal elements or reaches the ends of tuples. C++ Library - - These are objects that pack elements of -possibly- different types together in a single object, just like pair objects do for pairs of elements, but generalized C# Tuple ExamplesCreate tuples to store immutable data. C# unterstützt die Zuweisung zwischen Tupeltypen, die die beiden folgenden Bedingungen erfüllen: C# supports assignment between tuple types that satisfy both of the following conditions: Beide Tupeltypen haben die gleiche Anzahl von Elementen. So that leads us to…. both tuple types have the same number of elements. , as you suggested, we could use pattern matching to test: I.e., we deconstruct the result tuple into the variable `i` and test whether the second item is `true` at the same time. Die „Liste“ enhält bis zu 8 Elemente, welche über die Eigenschaften Item1, Item2etc. C# Queue with Examples; Linked List Implementation in C#; C# | Tuple Class. Well when we decompile the .NET code : So basically each create statement has been manually added up to 8. So for example : This can be useful if you are calling a library that returns a tuple but you ain’t about that and want individual variables. Circular Queue 3. The Tuple class was introduced in .NET Framework 4.0. Nature forms an unbroken chain. Im folgenden Beispiel wird gezeigt, wie Werte zu einem Queue erstellt und hinzugefügt werden und wie seine Werte gedruckt werden.The following example shows how to create and add values to a Queueand how to print out its values. A tuple is a data structure that contains a sequence of elements of different data types. Anstatt out-Methodenparameter zu definieren, können Sie also Methodenergebnisse in einem Tupelrückgabetyp gruppieren. Die Werte von Tupelelementen werden gemäß der Reihenfolge der Tupelelemente zugewiesen. Im folgenden Beispiel wird veranschaulicht, wie Sie eine Tupelvariable deklarieren, initialisieren und dafür auf die zugehörigen Datenmember zugreifen können:The following example shows how you can declare a tuple variable, initialize it, and access its data members: Wie im obigen Beispiel zu sehen ist, geben Sie zum Definieren eines Tupeltyps die Typen aller Datenmember und optional die Feldnamen an.As the preceding example shows, to define a tuple type, you specify types of all its data members and, optionally, the field names. Weitere Informationen finden Sie in den folgenden Hinweisen zu Featurevorschlägen: For more information, see the following feature proposal notes: Ableiten von Tupelnamen (Tupel-Projektionsinitialisierer), Infer tuple names (aka. Creating Modern And Helpful Command Line Utilities With System.CommandLine, Simplifying Multithreaded Scenarios With PostSharp Threading, Using Channels In C# .NET Core – Part 3 – Understanding Back Pressure, Using Channels In C# .NET Core – Part 2 – Advanced Channels, Using Newtonsoft.Json In .NET Core 3+ Projects, Creating Windows Services In .NET Core – Part 1 – The “Microsoft” Way, https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-7. Empty list is supported. Almost. Sie können Tupel mit einer beliebig großen Anzahl von Elementen definieren: You can define tuples with an arbitrary large number of elements: Einer der häufigsten Anwendungsfälle für Tupel ist die Verwendung als Methodenrückgabetyp. Dies ist normalerweise bei privaten und internen Hilfsmethoden hilfreich. The candidate name is a duplicate of another tuple field name, either explicit or implicit. Constructs an object of the appropriate tuple type to contain a concatenation of the elements of all the tuples in tpls, in the same order. The values passed should be in order with the values declared in … Mathematicians usually write tuples by listing the elements within parentheses "( )" and separated by commas; for example, (2, 7, 4, 1, 7) denotes a 5-tuple. Conceptually, they are similar to plain old data structures (C-like structs) but instead of having named data members, its elements are accessed by their order in the tuple. Dies wird im folgenden Beispiel veranschaulicht: You cannot define methods in a tuple type, but you can use the methods provided by .NET, as the following example shows: Beginning with C# 7.3, tuple types support, Weitere Informationen finden Sie im Abschnitt, Für das Feature „Tupel“ werden der Typ, To use tuples in a project that targets .NET Framework 4.6.2 or earlier, add the NuGet package. Each element can be of a different type. T… Tuple element values are assigned following the order of tuple elements. Simple Queue 2. Data Structures allows you to organize your data in such a way that enables you to store collections of data, relate them and perform operations on them accordingly. These operators compare members of the left-hand operand with the corresponding members of the right-hand operand following the order of tuple elements. To access values in tuple, use the square brackets for slicing along with the index or indices to obtain value available at that index. The candidate name is a member name of a tuple type, for example. return Tuple.Create("abc", 123); } void DoWork() { Console.WriteLine(GetData().Item1); } There is only one 0-tuple, referred to as the empty tuple. Template parameters Types... A list of types used for the elements, in the same order as they are going to be ordered in the tuple. Member functions (constructor) Construct tuple (public member function ) tuple::operator= Your email address will not be published. Access Tuple Elements. vom Namen der entsprechenden Variablen in einem Ausdruck für die Tupelinitialisierung abgeleitet (wie im folgenden Beispiel): Beginning with C# 7.1, if you don't specify a field name, it may be inferred from the name of the corresponding variable in a tuple initialization expression, as the following example shows: Dies wird als Tupel-Projektionsinitialisierer bezeichnet. The size of the tuple is fixed, since it cannot be changed once; it has been defined at the time when the tuple is created. Erwägen Sie bei Verwendung einer öffentlichen API, den Typ, In the case of public API, consider defining a. Sie können die Namen von Tupelfeldern entweder in einem Ausdruck für die Tupelinitialisierung oder in der Definition eines Tupeltyps explizit angeben. Available in C# 7.0 and later, the tuples feature provides concise syntax to group multiple data elements in a lightweight data structure. Queue() Initialisiert eine neue, leere Instanz der Queue-Klasse, die die Standardanfangskapazität aufweist. But they were complete crap and were more of a framework construct rather than being embedded in the language. For example if I passed in 9 parameters into my Tuple.Create statement : Things blow up. An example of a C# tuple is a data structure with three elements (known as a 3-tuple or triple) that is used to store an identifier such as a person's name in the first element, a year in the second element, and the person's income for that year in the third element. Weitere Informationen finden Sie im Abschnitt Tupelgleichheit.For more information, see the Tuple equality section. Operations on tuple:-1. get():- get() is used to access the tuple values and modify them, it accepts the index and tuple name as arguments to access a particular tuple element. For example − When the above code is executed, it produces the following result − Sie können die Namen von Tupelfeldern entweder in einem Ausdruck für die Tupelinitialisierung oder in der Definition eines Tupeltyps explizit angeben. Introduction of Javatuples 4. It stores the values in the order in which the values were added. It has a front and rear. Concatenation is done by the use of ‘+’ operator. Join over 3.000 subscribers who are receiving our weekly post digest, a roundup of this weeks blog posts. The answer is… It depends. It has the same kind if clarity as pattern matching. Happy for this to lead to comments saying I’m wrong. Pairs are a particular case of tuple. Organizing, managing and storingdata is important as it enables easier access and efficient modifications. Dies wird im folgenden Beispiel veranschaulicht:However, before any comparison, all tuple elements are evaluated, as the following example shows: Normalerweise gestalten Sie eine Methode, die out-Parameter enthält, in eine Methode um, die ein Tupel zurückgibt.Typically, you refactor a method that has out parameters into a method that returns a tuple. We can remove the dynamic object because IMO that’s easily the worse. Properties of tuple . Why? It *almost* means that if you are calling a method that returns a named tuple, your calling code can act as if it’s not a tuple at all and is instead a class. I can also see this being pretty useful instead of using out params. Bei Tupeln handelt es sich also um veränderliche Werttypen.That makes tuples mutable value types. the types of the elements that the tuple stores. Immutable- Like strings, tuples in C# are immutable, so once created; no modification is possible and the modification will lead to the creation of another tuple … This would look nicer than the `out` parameter in `TryParse`. An n-tuple is a sequence (or ordered list) of n elements, where n is a non-negative integer. It works a bit like so : Note that even if the method you are calling does not name the properties of the tuple, you can chose to do so yourself like so : There’s now this concept of “deconstruction” where we can take a tuple and turn it into individual variables. Concatenation of tuples is done always from the end of the original tuple. But adding a Tuple to start with in most cases is going to be a bad move. I still had a few posts which I was planning to write about first, but the simplicity and usefulness of the following discovery prompted me to go ahead and cut in line of my post queue. If you are creating a utility library and those library methods need to return more than one result but the creation of a return object for each method is too much, then a Tuple *could* be used (But doesn’t mean it should). Typically, you use tuples to group loosely related data elements. Das Feature Tupel ist in C# 7.0 und höher verfügbar und bietet eine überschaubare Syntax zum Gruppieren von mehreren Datenelementen in einer einfachen Datenstruktur.Available in C# 7.0 and later, the tuples feature provides concise syntax to group multiple data elements in a lightweight data structure. You can now name the properties inside the tuple by either naming it on the left hand side like : Or naming it on the right hand side like : This does away with the whole “Item1” business which was one of my main complaints about earlier versions of tuples. Available in C# 7.0 and later, the tuples feature provides concise syntax to group multiple data elements in a lightweight data structure. Sie können Tupel mit einer beliebig großen Anzahl von Elementen definieren:You can define tuples with an arbitrary large number of elements: Einer der häufigsten Anwendungsfälle für Tupel ist die Verwendung als Methodenrückgabetyp.One of the most common use cases of tuples is as a method return type. June 2, 2019 12:47 AM. Ab C# 7.3 unterstützen Tupeltypen die Operatoren == und !=.Beginning with C# 7.3, tuple types support the == and != operators. Die Standardnamen von Tupelfeldern lauten Item1, Item2, Item3 usw.The default names of tuple fields are Item1, Item2, Item3 and so on. We hate spam. That is usually useful within private and internal utility methods. verfügbar sind. However in C# 7, The ValueTuple struct type was added. Developers who aren’t already familiar with the way that tuples are used in other languages such as F#, Haskell, Python and Scala sometimes struggle with them in C#. In the .NET construct where you use Tuple.Create, you cannot set the value of an item. Die Standardnamen von Tupelfeldern lauten. I’m going to use our example of parsing an int earlier as it’s actually a good example of returning two pieces of data from a single method. Wie im obigen Beispiel zu sehen ist, werden Tupelfeldnamen bei Operationen mit == und != nicht berücksichtigt.As the preceding example shows, the == and != operations don't take into account tuple field names. 1 Synthesized three-way comparison; 2 Parameters; 3 Return value; 4 Example; 5 See also; Synthesized three-way comparison. Tuples were actually in .NET Framework before C# 7. For example − When the above code is executed, it produces the following result − tuple projection initializers), Auswählen zwischen anonymen Typen und Tupeltypen, Choosing between anonymous and tuple types, Dekonstruieren von Tupeln und anderen Typen. Dies bedeutet, dass eine Operation sofort angehalten wird, wenn ein Paar mit ungleichen Elementen erkannt oder das Ende von Tupeln erreicht wird.That is, an operation stops as soon as it meets a pair of non equal elements or reaches the ends of tuples. Operations on tuple:-1. get():- get() is used to access the tuple values and modify them, it accepts the index and tuple name as arguments to access a particular tuple element. Tuples were introduced in C# 4.0. Es gibt aber auch Fälle, in denen ein out-Parameter einen Tupeltyp aufweisen kann.However, there are cases in which an out parameter can be of a tuple type. Your email address will not be published. For example, imagine if int.TryParse was reworked to look like : I mean maybe not that much of an improvement, but we can see how it could be useful if you don’t want to use Tuples at all but are forced to calling a method that does use them. This is probably very rarely going to come up as we go forward since it’s unlikely you will use the old Tuple construct, but it’s something to be aware of. Parameters tpls Comma-separated list of tuple … Dies ist normalerweise bei privaten und internen Hilfsmethoden hilfreich.That is usually useful within private and internal utility methods. Priority Queue 4. Daher sind explizit angegebene oder abgeleitete Feldnamen zur Laufzeit nicht verfügbar. And on that 8th statement you can actually add a Tuple as the final param to have a nested Tuple. That's known as tuple projection initializers. In diesen Fällen geben Sie entweder explizit den Namen eines Felds an oder greifen über den Standardnamen auf ein Feld zu. The following behavior-changing defect reports were applied retroactively to previously published C++ standards. Each element in the returned tuple is copy/move constructed (as if passed with forward). Zwei Tupel sind vergleichbar, wenn die beiden folgenden Bedingungen erfüllt sind:Two tuples are comparable when both of the following conditions are satisfied: Die Operatoren == und != vergleichen Tupel per „Kurzschluss“.The == and != operators compare tuples in short-circuiting way. I used the example of parsing an integer above because I think it’s one of the few cases where it might be reasonable to use. Der Name einer Variablen wird in den folgenden Fällen nicht auf einen Tupelfeldnamen projiziert: The name of a variable isn't projected onto a tuple field name in the following cases: Der Kandidatenname ist ein Membername eines Tupeltyps, z. B. Den Standardnamen eines Felds können Sie immer verwenden. But C# provides a Tuple class that can be used and can be a more efficient way to return multiple values from a function. Sie können Tupeltypen auch anstelle von anonymen Typen verwenden, z. B. in LINQ-Abfragen.You can also use tuple types instead of anonymous types; for example, in LINQ queries. Sie sind in .NET Core sowie in .NET Framework 4.7 und höher verfügbar.The tuples feature requires the System.ValueTuple type and related generic types (for example, System.ValueTuple), which are available in .NET Core and .NET Framework 4.7 and later. Ontop of that, there was this weird (Atleast I thought so initially) limit of 8 items within the tuple. Unless they are familiar with a dynamically-typed or functional language, object-oriented developers understandably question the tuple’s raison d’être. Dies wird im folgenden Beispiel veranschaulicht: The names of tuple fields are ignored and not assigned, as the following example shows: Hierfür können Sie eine der folgenden Vorgehensweisen wählen: You can do that in one of the following ways: Explizites Deklarieren des Typs jeder Variablen in Klammern: Explicitly declare the type of each variable inside parentheses: Weitere Informationen zur Dekonstruktion von Tupeln und anderen Typen finden Sie unter, For more information about deconstruction of tuples and other types, see, Ab C# 7.3 unterstützen Tupeltypen die Operatoren, Beginning with C# 7.3, tuple types support the. vom Namen der entsprechenden Variablen in einem Ausdruck für die Tupelinitialisierung abgeleitet (wie im folgenden Beispiel):Beginning with C# 7.1, if you don't specify a field name, it may be inferred from the name of the corresponding variable in a tuple initialization expression, as the following example shows: Dies wird als Tupel-Projektionsinitialisierer bezeichnet.That's known as tuple projection initializers. Yep, out methods themselves have been much more easier to use with the in-line variable declaration. Search accomplished by using a queue that tracks current node being reviewed and what level that node came from within the tree. Tuples were actually in .NET Framework before C# 7. The fact you had to have the Tuple object be the return type as well made it feel like it was hardly more appealing than just returning a list, dictionary, or some other data structure that is simply a “list” of items. In almost all cases, I would start with a return class, and only then if that doesn’t look right, try a Tuple. Mit diesen Operatoren werden Member des linken Operanden gemäß der Reihenfolge der Tupelelemente mit den entsprechenden Membern des rechten Operanden verglichen.These operators compare members of the left-hand operand with the corresponding members of the right-hand operand following the order of tuple elements. For example, you could do something like so : Tuple GetData() { return new Tuple("abc", 123); //Alternatively. Soon as it meets a pair of non equal elements or reaches the ends tuples!
