Check Balanced Parentheses in Python
This program checks if a given string of parentheses is balanced. A balanced string of parentheses means that each opening symbol has a corresponding closing symbol and the pairs of…
Queue Implementation Using Linked List in Python
This program demonstrates the implementation of a queue data structure using a linked list. Queues are a type of data structure with First In First Out (FIFO) access policy. The…
Stack Implementation Using Linked List in Python
This program demonstrates the implementation of a stack data structure using a linked list. Stacks are a type of data structure with Last In First Out (LIFO) access policy. The…
Java Program to Implement a Stack Using an Array

Java Program to Implement a Queue Using an Array
This program demonstrates how to implement a basic queue using an array. A queue is a First In First Out (FIFO) data structure where elements are added to the rear…
Java Program to Check Balanced Parentheses
This program demonstrates how to check if a string containing different types of parentheses (i.e., ‘(‘, ‘)’, ‘{‘, ‘}’, ‘’) is balanced. A balanced string has matching opening and closing…
Java Program to Find the Next Greater Element in an Array
This program demonstrates how to find the next greater element for each element in an array using a stack data structure. The next greater element for an element x is…
Java Program to Implement a Stack with Min Functionality
This Java program demonstrates how to implement a stack that supports pushing, popping, and retrieving the minimum element in constant time. The stack uses an auxiliary stack to track the…
Java Program to Implement a Circular Queue
This Java program demonstrates how to implement a circular queue using an array. A circular queue is a linear data structure that follows the principle of FIFO (First In First…
