The problem is opposite of this post. We are given a stack data structure with push and pop operations, the task is to implement a queue using instances of stack data structure and operations on them....
In C++ STL, a map is a container that stores key-value pairs in an ordered or sorted manner. In this article, we will learn how to find the first key-value pair in a Map....
In C++, sets are a type of associative container in which each element has to be unique because the value of the element identifies it. The values are stored in a specific sorted order i.e. either ascending or descending. In this article, we will learn how to find the last element in a set in C++....
