Best Case Analysis
****************
- The best case of quicksort occurs when the pivot we pick happens to divide the array into two exactly equal parts , in every step.
- The best case for quick sort happen when the list is partition into balance segment
- Must chose the right pivot that can put other items in balance situation
- The best case for quick sort happen when the left segment and the right segment is balanced (have the same size) with value x ≈ lg n
The partitioning operations on each level of the elements is O(n) and there will be log n levels of equal partition to become single element partitions. Hence ,
Complexity for Best Case : O(n log n)

quick SORT
The efficeieny of the quicksort depends on the pivot element. However the pivot element can also be choosen at random order or from the last element of the array
