Finding the Next Greater Element in C
This program finds the next greater element for each element in a given array. The Next Greater Element (NGE) for an element x is the first greater element to the…
Stack Design with Minimum Element Retrieval in C
This program implements a stack that supports the standard stack operations like push and pop, along with an additional feature to retrieve the minimum element in the stack in constant…
Circular Queue Implementation in C
A circular queue is a linear data structure that operates in a circular fashion. Unlike a normal queue where the rear pointer moves only in one direction, in a circular…
Least Recently Used (LRU) Cache Implementation in C
An LRU (Least Recently Used) cache is a data structure that stores a fixed number of elements. When the cache reaches its limit, it evicts the least recently used item…
Evaluate Postfix Expression Using a Stack in C
This program evaluates a postfix expression using a stack. A postfix expression (also known as Reverse Polish Notation) is a mathematical expression where the operator follows its operands. For example,…
Sorting Stack Using Another Stack in C
This program demonstrates how to sort the elements in a stack using another temporary stack. The idea is to use the main stack for pushing elements and another stack to…
Sliding Window Maximum in C
This program finds the maximum element in each sliding window of size k for a given array. The sliding window moves one element at a time from left to right,…
Implementing a Stack using an Array in C++
This C++ program demonstrates how to implement a stack using an array. A stack is a LIFO (Last In First Out) data structure used in various programming scenarios. Program Code…
Implementing a Queue using an Array in C++
