Visually Explained Algorithms Like most sorting algorithms, the Quick Sort algorithm sorts an array of items in ascending order. There are numerous approaches to Quick Sort. This article will focus on one method. T his approach selects the left-most element of the array as the pivot. It then compares it against the last element in the array. If the pivot is less than the element it’s being compared to, that element becomes the pivot and the left side is incremented. If the pivot is greater than the element it’s being compared to, the index value of that element is incremented. This occurs until
