About this video

Quick sort is a popular sorting algorithm invented by British scientist Tony Hoare. Often interviewers ask questions around quick sort in software engineering interviews. This technique uses divide and conquer approach to divide given list into partitions and then recursively sort these partitions. It starts with a pivot element and tries to put pivot element in its correct position. This video goes over theory and two popular partition schemes called hoare partition and lomuto partition. We will write code to implement quick sort algorithm in python. In the end I have an exercise for you to solve.
