Question

Quick Sort is another divide and conquer algorithm (similar to Merge Sort) that essentially splits the list recursively. Briefly (in one sentence) state how Quick Sort splits the list.

A) By partitioning elements around a pivot
B) By splitting into smaller and larger sublists
C) By comparing adjacent elements and swapping
D) By selecting the median element as the pivot

Answer 1

Quick Sort partitions a list by selecting a pivot element and arranging all elements less than it to the left and all greater to the right, creating sublists for recursive sorting.

Step-by-step explanation:

Quick Sort splits the list by partitioning elements around a pivot, where the pivot is an element chosen from the array (it could be the first, last, middle, or a random element). The partition process involves moving all elements less than the pivot to its left and all greater elements to its right. This effectively creates two sublists which are then recursively sorted using the same algorithm.
