https://leetcode.com/problems/sudoku-solver/ 题意分析: 这次的题目就是上一题的进化版。填好一个数独。 题目思路: 这题直接用dfs暴力解决。把“*”用(1-9)直接填就行。时间复杂度比较高。要注意的是,题目要求没有返回值,所以要另外写一个函数用来判断填数之后是否满足可以填好。 代码(python): View C...

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. ...
Sudoku Solver@LeetCode Sudoku Solver 题目看起来有些难,但是其实解法很通俗,就是每一步就尝试一遍所有9个数字,然后看哪个数字是可以当前合理的。 主体还是一个递归函数,找出当前适合的数后再递归调用。找出合适的数的方法就是遍历9个数字填充到当前位置,然后用验证函数进行验证,然后验证通过就继续调用递归函数解出...
