def main2():
....res = 0
....for row in mapData:
........isOne = False
........for j, element in enumerate(row):
............if not isOne and element == 1:
................isOne = True
................res += j
............elif isOne and element == 0:
................isOne = False
................res += (j - 1)
........if isOne:
............res += j
这样遍历快一点
