// Suppose that their exists a direction(vertically or horizontally) in which
// the steps remaining to arrive at the destination (n-1 or m-1) is even, as long
// as Kiki adjusts the position of the chess to the following parity at first, he
// always has the priority of keeping the parity in both directions unchanged (even)
// every time it‘s ZZ‘s turn until the chess reaches the terminal and ZZ is trapped.
// On the opposite occasion, ZZ will have that priority so that Kiki will lost
// the game.
