Tell me about Quick sort

Question

Accepted Answer

Quick sort is a popular sorting algorithm that uses a divide-and-conquer approach to sort elements in an array.

Quick sort picks a 'pivot' element from the array and partitions the other elements into two sub-arrays according to whether they are less than or greater than the pivot.
It then recursively sorts the sub-arrays.
The pivot selection can greatly affect the efficiency of the algorithm. Commonly used methods include selecting the first element as the pivot, the last element, or a random element.
Quick sort has an average time complexity of O(n log n), making it one of the fastest sorting algorithms.
Example: Given an array of strings ['apple', 'banana', 'cherry', 'date'], after applying quick sort, the array could be sorted as ['apple', 'banana', 'cherry', 'date'].
