Quick sort works by separating a list into two lists, and recursively sorting the two lists using quick sort. A. True B. False

Answer

A. True

Explanation

Quick sort is indeed an efficient sorting algorithm that operates on the principle of divide-and-conquer. It works by selecting a 'pivot' element from the array and partitioning the other elements into two sub-arrays: those less than the pivot and those greater than the pivot. This partitioning process results in two lists, which are then recursively sorted using the same quick sort algorithm. The recursion continues until the base case is reached, where the list is either empty or contains a single element, at which point it is already sorted. Quick sort is known for its average-case time complexity of $O(n \log n)$, making it a popular choice for sorting large datasets.
