Here's my own C# implementation! ✌ Thanks everyone for your participation! To be honest I've hard time for picking the best answer this round as there are a few straight-forward and creative algorithms. Anyway let's move on to the next challenge! ❤ https://code.sololearn.com/cX4A7UssFE69/?ref=app https://www.sololearn.com/Discuss/774727/?ref=app
