WebJan 11, 2024 · The most common example is partitioning an array of numbers based on a pivot number, so that all elements on the left side of the array are less than or equal to the pivot, while all elements on the right are greater than the pivot. This specific procedure is crucial for quicksort, a popular and efficient sorting algorithm. WebAlgorithm or Procedure: First, from the given subpart of the array randomly pick the pivot element. Now we need to partition the element around the pivot such that smaller elements should come to the left of the pivot and larger elements to the right of the pivot. We need to consider these left and right subparts as new sub-array.
