Paint some cells black so that every arrow points to exactly the corresponding number of black squares. Black squares cannot touch each other from the sides but they may touch diagonally, and all remaining white cells not occupied by an arrow or not blackened should be traversed by a single closed loop that connects the centers of adjacent squares and doesn’t cross itself. Draw the loop and blacken all the necessary squares.
