Time and Space Complexity Analysis of Quick Sort
https://www.geeksforgeeks.org/time-and-space-complexity-analysis-of-quick-sort/
Best Case Time Complexity Analysis of Quick Sort: O (N * logN) The best case occurs when we select the pivot as the mean. So here. T (N) = 2 * T (N / 2) + N * constant. Now T (N/2) is also 2*T (N / 4) + N / 2 * constant. So, T (N) = 2* (2*T (N / 4) + N / 2 * constant) + N * constant. = 4 * T (N / 4) + 2 * … See more
