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++, we have a stack data structure that follows the Last In First Out (LIFO) principle. In this article, we will learn how to reverse a word using a stack in C++....

In C++, a vector can be traversed in reverse order using a const_reverse_iterator. A const_reverse_iterator is a type of iterator that points to the last element in the container and moves in the reverse direction. In this article, we will learn how to traverse a vector using a const_reverse_iterator in C++....

Given a vector V consisting of N integers and an element K, the task is to find the index of element K in the vector V. If the element does not exist in vector then print -1....

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....

In C++, Stacks are a type of container adaptor with LIFO(Last In First Out) type of working, where a new element is added at one end (top) and an element is removed from that end only. In this article, we will learn how to declare a stack in C++....

The ‘=’ is an operator in C++ STL which copies (or moves) an unordered_set to another unordered_set and unordered_set::operator= is the corresponding operator function. There are three versions of this function....

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++, multimap stores key-value pairs and for the same key there can be multiple values in a multimap. In this article, we will learn how to delete a pair from a multimap in C++....
