Q. Explain quick sort and its complexity.
Ans. 

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

  • The complexity of quick sort is O(n log n) on average and O(n^2) in worst case scenario.

  • Example: [5, 2, 9, 3, 7, 6] -> [2, 3, 5, 6, 7, 9]
