WebQuick Sort. Quick Sort is a Divide and Conquer algorithm. It picks an element as a pivot and partitions the given array around the picked pivot. Given an array arr [], its starting position is low (the index of the array) and its ending position is high (the index of the array). Note: The low and high are inclusive. WebHeap sort is an efficient comparison-based sorting algorithm that: Creates a heap from the input array. Then sorts the array by taking advantage of a heap's properties.
