This is my first attempt at implementing an exercise and it seems like a good one to try. May I have this assigned to me and do you know of another language which has this exercise that I can copy from?

Thank you @CliffRoberson for the help.
I found a go implementation of this problem if it can help you.

Feel free to ask for every doubt
