A chess rook is on the leftmost cell of the 1×30 lane and can move any number of cells, but only to the right. In how many ways can the rook move to the rightmost cell?
try drawing a chessboard first.
do you know the answer because I need it for tomorrow and it makes no sense to me.
I was still stuck
A 1 * 30 lane? I am confused, a chess board is 8 * 8
is there a picture that comes with the problem?
