Heap Sort Algorithm: Step by Step Guide with C++ Code

Heap sort is a comparison-based sorting algorithm that uses a binary heap data structure to sort elements. It is one of the most efficient sorting algorithms, with a time complexity of O(n*logn) and a space complexity of O(1). In this blog, we will discuss the Heap sort

Binary Search Algorithm: A Powerful Tool for Searching Large Data Sets

Binary search is one of the most important algorithms in computer science, and is used to search for a specific value in a sorted array or list. It is an efficient algorithm that works by repeatedly dividing the search interval in half, eliminating the half where the target value cannot
