The deque::rend() is an inbuilt function in C++ STL which returns a reverse iterator which points to the position before the beginning of the deque (which is considered its reverse end)....

In C++, a deque (double-ended queue) is a container that allows insertion and removal of elements from both ends whereas an unordered set is a container that stores unique elements in no particular order. In this article, we will learn how to create a deque of unordered sets in C++ STL....

In C++, deques also known as double-ended queues are sequence containers with the feature of insertion and deletion on both ends. In this article, we will learn how to find the first occurrence of a specific element in a deque in C++....

In C++, deques also known as double-ended queues are sequence containers that allow the users to insert and delete elements from both ends efficiently. In this article, we will learn how to find the last occurrence of a specific element in a deque in C++....

In C++, a deque (double-ended queue) is a data structure that allows efficient insertion and deletion at both ends. In this article, we will learn to remove an element from the beginning of a deque in C++....

In C++, deques are sequence containers similar to queues but unlike queues, deques allow the insertion and deletion of elements from both ends efficiently. Vectors are dynamic arrays that can resize themselves during the runtime. In this article, we will learn how to create a deque of vectors in C++....

In C++, a deque is a flexible data structure that supports the insertion and deletion of elements from both ends efficiently. In this article, we will learn how to add an element at the end of a deque in C++....

In C++, deques are containers that allow efficient insertion and deletion operations from both ends. Multisets are associative containers similar to sets but unlike sets, multisets allow duplicate insertions as well. In this article, we will learn how to create a deque of multiset in C++....

In C++ STL, a container called deque (known as a double-ended queue) allows us to insert and delete elements at both its beginning and its end. In this article, we will learn how to remove a specific element from a deque in C++ STL....

Double-ended queues are sequence containers with the feature of expansion and contraction on both ends. They are similar to vectors but are more efficient in the case of insertion and deletion of elements at the front and end. In this article, we will learn how to find the frequency of a specific element in a deque in C++....

In C++, both deque and vector are sequence containers that can be used to store collections of elements. However, there are some cases where using deque can be more beneficial than using vector. In this article, we will learn when to use deque instead of vector in C++....

In C++, a deque (double-ended queue) is a container class template that allows fast insertion and deletion at both its beginning and end. In this article, we will learn how to find the average (or mean) of all elements in a deque in C++....
