def is_peak(map, r, c): Given a map and a location, is it land and are all neighboring land spots lower than it? If the spot isn't on the map, it is not a peak. It's possible to have peaks on the border. Assume: map is a map as defined above, and r and c are int values. is_peak(map2,1,3) True is_peak(map2,2,3) False is_peak(map5,3,3) True

def on_map(map, r, c): if r >= 0 and c >= 0 and r
