The topic I chose is sorting algorithms. I The algorithm that I'll be profiling and analyzing would be a merge sort algorithm written in c++ which can be found [https://codereview.stackexchange.com/questions/128457/recurrent-merge-sort-without-recursion/ Here]. This code would ask the user to input the size of the array and then fill the array with random elements. The size of the array can be extremely large. From the original creator, the size of the array entered was in the tens of thousands. Theoretically, there would be no limit to how much the user can input however the original creator of this code said it would take him the user several hours to sort 10 million elements in the entered array.
