COM-B1-M06-P018 Knight After Odd Moves
#18
★★★☆☆ Level 3 of 5
A knight stands on a white square of a chessboard. Can it be on a white square after \(2025\) moves?
Every knight move changes the square color.
A knight move changes the square color. After an odd number of moves, the color is opposite to the initial one. Since \(2025\) is odd, the knight is on a black square, not white.
Color plus move parity.
