为什么，哪里有问题？求大佬点播我 n, m, k = map(int, input().split()) matrix = [[0] * n for _ in range(n)] # 构建一个二维矩阵，0表示暗的，1表示亮的

for i in range(m): # 火把 x, y = map(int, input().split()) row = x - 1 col = y - 1 matrix[row][col] = 1 # 矩阵是从0开始的 if 0 <= row - 1 < n and 0 <= col - 1 < n: matrix[row - 1][col - 1] = 1 if 0 <= row - 1 < n and 0 <= col + 1 < n: matrix[row - 1][col + 1] = 1 if 0 <= row + 1 < n and 0 <= col - 1 < n: matrix[row + 1][col - 1] = 1 if 0 <= row + 1 < n and 0 <= col + 1 < n: matrix[row + 1][col + 1] = 1 # 行变 for l in range(n): # 将这里的k改为l，避免和外层的k冲突 if l!= col: matrix[row][l] = 1 # 列变 for j in range(n): if j!= row: matrix[j][col] = 1

for j in range(k): a, b = map(int, input().split()) row = a - 1 col = b - 1 # 处理萤石所在5*5格子位置变亮（注意边界判断） for i in range(max(0, row - 2), min(n, row + 3)): for c in range(max(0, col - 2), min(n, col + 3)): # 将这里的j改为c，避免变量冲突 if 0 <= i < n and 0 <= c < n: # 增加这层判断，确保在矩阵范围内 matrix[i][c] = 1

count = 0 for line in matrix: for num in line: if num == 0: count += 1

print(count)
