Question

I am confused about how to code this. I have tried multiple ways of coding this and nothing has worked for me. If someone could help that would be great thanks.

/*Chess Board:

You will also create 5 "lanes" of "pieces" and each lane has that number of pieces on it;
i.e. lane 5 = 5 pieces, lane 4 = 4 pieces, etc.
The user and the computer can take any number of pieces from one lane.
The object is to not take the last piece. Will it matter who goes first?*/
