下面是一个用Python编写的数独游戏的示例代码:
```python
import random
class Sudoku:
def __init__(self, board):
self.board = board
def solve(self):
for i in range(9):
for j in range(9):
if self.board[i][j == 0:
for k in range(1, 10):
if self.is_valid(i, j, k):
self.board[i][j = k
if self.solve():
return True
self.board[i][j = 0
return False
return True
def is_valid(self, row, col, num):
# 检查行是否合法
for i in range(9):
if self.board[row][i == num:
return False
# 检查列是否合法
for j in range(9):
if self.board[j][col == num:
return False
# 检查九宫格是否合法
start_row = (row // 3) * 3
start_col = (col // 3) * 3
for i in range(3):
for j in range(3):
if self.board[start_row + i][start_col + j == num:
return False
return True
def generate_board(grade):
board = [[0 * 9 for _ in range(9)]
for i in range(9):
b = [x for x in range(9)]
random.shuffle(b)
for j in range(grade):
board[i][b[j]] = 0
return board
# 生成一个答案数独作为题面
board = generate_board(0)
# 创建数独对象
sudoku = Sudoku(board)
# 解决数独
sudoku.solve()
# 打印数独题面
for row in sudoku.board:
print(row)
```
这段代码实现了一个数独游戏的解决器。首先定义了一个Sudoku类,其中solve函数使用回溯算法来解决数独游戏。is_valid函数用于检查某个位置是否可以放置一个数字。generate_board函数用于生成一个标准数独作为题面,并随机挖空一定数量的数字。最后,创建一个Sudoku对象并调用solve函数来解决数独游戏,然后打印出题面的结果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
