  This C++ program checks if a string consisting of parentheses is balanced. A string of parentheses is considered balanced if every type of bracket […]

  This C++ program finds the next greater element for each element in an array. The next greater element for an element x is the […]

  This C++ program implements a stack that supports standard stack operations (push and pop), along with retrieving the minimum element in constant time. This […]

  A circular queue is a linear data structure that follows the First In First Out (FIFO) principle but unlike a traditional queue, the last […]

  This C++ program implements a Least Recently Used (LRU) cache. The LRU cache mechanism is used to maintain a set of items such that […]

  This C++ program demonstrates how to evaluate a postfix expression using a stack. Postfix, or reverse Polish notation (RPN), is a mathematical notation wherein […]

  This C++ program demonstrates how to sort a stack using only another temporary stack. The program sorts the original stack in ascending order where […]
