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…
Java Program to Implement an LRU Cache
An LRU (Least Recently Used) cache is a cache eviction algorithm that discards the least recently used items first when the cache is full. This Java implementation uses a HashMap…
Java Program to Evaluate a Postfix Expression Using a Stack
This Java program demonstrates how to evaluate postfix expressions using a stack. Postfix notation, also known as Reverse Polish Notation (RPN), is a mathematical notation in which every operator follows…
Java Program to Sort a Stack Using Another Stack
This Java program demonstrates how to sort elements in one stack using another temporary stack. The algorithm leverages the properties of the stack to reverse the order of elements such…
Java Program to Find Maximum in Sliding Window
This Java program uses a deque to solve the problem of finding the maximum in each sliding window of size k within a given array. The deque stores indices of…
Implementing In-order, Pre-order, and Post-order Traversals in a Binary Tree
This program demonstrates how to perform in-order, pre-order, and post-order traversals on a binary tree in C, displaying nodes in each traversal order. Program Explanation The program is structured into…
Level Order Traversal of a Binary Tree
This C program demonstrates how to perform a level order traversal on a binary tree, processing nodes level by level from top to bottom and left to right. Program Explanation…
