Q4. 3rd Array Sorting Algorithm
Ans. 
Quick Sort is a popular in-place sorting algorithm that uses divide and conquer approach.
• Divide the array into two sub-arrays based on a pivot element

• Recursively sort the sub-arrays

• Combine the sorted sub-arrays to get the final sorted array

• Time complexity: O(nlogn) in average case and O(n^2) in worst case

• Space complexity: O(logn)

• Example: [5, 2, 9, 3, 7, 6, 8] -> [2, 3, 5, 6, 7, 8, 9]
