def check_vertical (board, r, c): Does a run begin here and extend vertically down? If the location is invalid or a run doesn't start here, return False. If it does, return True. . Assume: board is a valid board, r and c are ints. Note: We aren't checking the entire column; we also don't mind if pieces above also match the run check-vertical([[A'], . check-vertical([[A'], . check-vertical([[A'], [A'], [A'], [A'], [A'], [A'], [A'], [A'], [A'], [A'], [A']], [A']], [A']], , ) 3, 0) -1, -1) True False False #not a full run #invalid location
