In some cells of a \(10 \times 10\) board, there are fleas. Every minute, the fleas jump simultaneously to an adjacent cell (along the sides). Each flea jumps strictly in one of the four directions parallel to the sides of the board, maintaining its direction as long as possible; otherwise, it changes to the opposite direction. Dog Barbos observed the fleas for an hour and never saw two of them on the same cell. What is the maximum number of fleas that could be jumping on the board?
