Example of merge sort
WebJan 17, 2024 · Well, let’s use merge sort!😎 That’s the beauty of recursion: We apply merge sort on the big array to sort the numbers. While doing this, merge sort is called two more times on smaller arrays, which in turn call merge sort four more times in total, and so on. We are passing on the problem. But at some point, we have to deliver something. WebBoth merge sort and quicksort employ a common algorithmic paradigm based on recursion. This paradigm, divide-and-conquer, breaks a problem into subproblems that are similar to the original problem, recursively solves the subproblems, and finally combines the solutions to the subproblems to solve the original problem.Because divide-and-conquer solves …
