Provide a correct Python 3 solution for this coding contest problem.
There is a knight - the chess piece - at the origin (0, 0) of a two-dimensional grid.
When the knight is at the square (i, j), it can be moved to either (i+1,j+2) or (i+2, j+1).
In how many ways can the knight reach the square (X, Y)?
