LeetCode.jpg 37. 解数独 编写一个程序,通过已填充的空格来解决数独问题。 一个数独的解法需遵循如下规则: 数字1-9在每一行只能出现一次。 数字1-9在每一列只能出现一次。 数字1-9在每一个以粗实线分隔的3x3宫内只能出现一次。 空白格用'.'表示。
写代码解决数独问题。 A sudoku solution must satisfyall of the following rules: 数独规则如下: Each of the digits1-9must occur exactly once in each row. 1-9每行必须出现且只能出现一次 Each of the digits1-9must occur exactly once in each column. ...
