蓝桥Python真题——扫雷

下面讲讲普通python语法中的IO运用

输一行字符串包含两个数据，将两个数据提取出来
n, m = map(int, input().split()
输入n行m列的二维矩阵数组

python 复制代码

gird = []
for _ in range(n): #n行
	row = list(map(int, input().split())) #m列
	gird.append(row)

声明一个元素都为0的二维数组
result = [[0 for _ in range(m)] for _ in range(n)]
内层是列数，外层是行数。
n行m列
遍历结果矩阵的每一行，转换为字符串，并用空格分隔后打印

python 复制代码

for row in result:
	print(' '.join(map(str, row)))

代码

python 复制代码

def main():
  n, m = map(int,input().split())
  gird = []
  for _ in range(n):
    row = list(map(int, input().split()))
    gird.append(row)
  directions = [
    (-1, -1), (-1, 0), (-1, 1),
    (0, -1),           (0, 1),
    (1, -1),  (1, 0),  (1, 1)
  ]
  result = [[0 for _ in range(m)] for _ in range(n)]

  for i in range(n):
    for j in range(m):
      if gird[i][j] == 1:
        result[i][j] = 9
      else :
        count = 0
        for dx, dy in directions:
          x = i+dx
          y = j+dy
          if 0<=x<n and 0<=y<m and gird[x][y]==1:
            count += 1
        result[i][j] = count

  for row in result:
    print(' '.join(map(str, row))) 

if __name__ =='__main__':
  main()

全是暴力，主要就是通过判断八个方向的地雷数。

也是因为题目的数据量不大。
