NettetJust like the merge sort and quicksort, we are going to apply recursion to implement the program, one of the major benefits of using recursion is that it is extremely fast, one downside could be that we need refinement of data, for example, in the case of binary search, we need sorted data in order to implement recursion.. In the python program, …
