Merge Sort is a Divide and Conquer algorithm that divides the array into halves, recursively sorts each half, and then merges the sorted halves. 📖 It was invented by John von Neumann in 1945 and is considered one of the most efficient sorting algorithms for large datasets. Why Use Merge Sort? How Does Merge Sort … Read more
Heap sort is an efficient sorting algorithm that uses heap data structure. The key idea behind heap sort is to transform the unsorted array into a heap structure, which is a complete binary tree. And then delete elements from the root of the heap in each iteration. The idea is to build a Min Heap … Read more
Selection Sort is a simple comparison-based sorting algorithm. It divides the input list into two parts: the sublist of items already sorted, which is built up from left to right at the front (left) of the list, and the sublist of items remaining to be sorted that occupy the rest of the list. Initially, the … Read more
