https://leetcode-cn.com/problems/sudoku-solver/ 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。 一个数独。 答案被标成红色。
在这动荡的日子里,也希望写点东西让自己静一静。恰好前段时间用python做了一点时间序列方面的东西,有一丁点心得体会想和大家分享下。在此也要特别感谢顾志耐和散沙,让我喜欢上了python。 什么是时间序列 时间序列简单的说就是各时间点上形成的数值序列,时间序列分析就是通过观察历史数据预测未来的值。在这里需要强调...

[LeetCode]题解(python):037-Sudoku Solver 题目来源: 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...
method:字符串或OdeSolver,可选 使用的积分方法: ‘RK45’ (default): Explicit Runge-Kutta method of order 5(4)[1]. The error is controlled assuming accuracy of the fourth-order method, but steps are taken using the fifth-order accurate formula (local extrapolation is done). A quartic interpo...
