Final answer:
Quick sort uses a pivot element to divide the list into two sub-arrays based on their values relative to the pivot before recursively sorting the sub-arrays.
Step-by-step explanation:
Quick sort splits the list by selecting a pivot element and partitioning the other elements into two sub-arrays according to whether they are less than or greater than the pivot.
Quick sort is a divide and conquer algorithm used to sort a list. It works by selecting a pivot element from the list and partitioning the other elements into two sub-arrays, according to whether they are less than or greater than the pivot.
