Add an algorithm

The program should be your own, no plagiarism shall be entertained. Try to add different PRs for different concepts so that reviewing them is easier and quicker. Make sure to name the program according to the concept/algorithm it tends to apply followed by your name.
Try to write the Time complexity (and space complexity too if possible) in the description.
