Problem Statement:  Given a vector find the minimum element of the vector. Example: Example 1: Input: arr = {3,1,9,5,2} Output: 1 Explanation: 1 is the minimum element. Example 2: Input: arr =...

Sorting is one of the most standard operations used very frequently while writing programs. Writing the complete sorting algorithm might be time consuming and hence STL provides us with a standard...

Problem Statement: Given a vector find the maximum element of the vector. Example: Example 1: Input: arr = {3,1,9,5,2} Output: 9 Explanation: 9 is the maximum element. Example 2: Input: arr = {10,4...

Introduction The problem of counting set bits in an integer means finding the number of 1’s in its binary representation. For example, the binary form of 7 is 111 , which has 3 set bits. Naive So...

What is Priority Queue? In the case of the max heap, priority queues are a type of container adaptors, specifically designed such that its first element is always the greatest of the elements it co...

What is Deque? Double Ended Queue which is also called Deque is a type of queue data structure in which the insertion and deletion of elements can be either in front or rear.  Deque in STL . Synta...

next_permutation in STL is a built-in function which as the name suggests returns the next lexicographically greater permutation of the elements in the container passed to it as an argument. Does i...

What is a List? A list in STL is a contiguous container that allows the inserting and erasing of elements in constant time and iterating in both directions. Syntax: list<object_type> variable...

What is a multimap in C++ STL? multimap in STL are associative containers like maps where each element consists of a key value and a mapped value, the only difference is multimaps can store duplica...

What is Stack? A stack is a non-primitive linear data structure. it is an ordered list in which the addition of a new data item and deletion of the already existing data item is done from only one...
