The topic for today is QuickSort!

• Quicksort is a divide & conquer algorithm.
• It uses recursion to sort the elements.
• It considers pivot element as a base value and sorts rest of the elements.

Pseudocode

1. Base condition: Return the array as it is if the array length is equal to 1.
2. Identify the pivot value
3. Get all the elements less than the pivot value on one side.
4. Get all the elements greater than the pivot value on another side.
5. Repeat steps 2,3 & 4
6. Return final sorted array
