Check Balanced Parentheses in C++
This C++ program checks if a string consisting of parentheses is balanced. A string of parentheses is considered balanced if every type of bracket (curly, square, round) is closed and…
Find Next Greater Element in an Array – C++
This C++ program finds the next greater element for each element in an array. The next greater element for an element x is the first greater element on the right…
Min Stack Implementation – C++
This C++ program implements a stack that supports standard stack operations (push and pop), along with retrieving the minimum element in constant time. This is achieved by using an auxiliary…
Implementing a Circular Queue in C++
A circular queue is a linear data structure that follows the First In First Out (FIFO) principle but unlike a traditional queue, the last position is connected back to the…
Least Recently Used (LRU) Cache Implementation – C++
This C++ program implements a Least Recently Used (LRU) cache. The LRU cache mechanism is used to maintain a set of items such that the least recently used items are…
Evaluate Postfix Expression Using a Stack – C++ Implementation
This C++ program demonstrates how to evaluate a postfix expression using a stack. Postfix, or reverse Polish notation (RPN), is a mathematical notation wherein every operator follows all of its…
Sort Stack Using Another Stack – C++ Implementation
This C++ program demonstrates how to sort a stack using only another temporary stack. The program sorts the original stack in ascending order where the smallest elements end up on…
Sliding Window Maximum – C++ Implementation
Sliding Window Maximum – C++ Implementation This C++ program finds the maximum value in each sliding window of size k in a given array using an efficient method. #include #include…
Trie (Prefix Tree) Implementation in C++
Trie (Prefix Tree) Implementation in C++ A Trie (pronounced as “try”) is a tree-like data structure used to store a dynamic set of strings, where the keys are usually strings.…
