难度:90. 非常不错的一道一维DP题目,参考了网上的做法。 看到这种求数量的,我们很容易想到动态规划来存储前面信息,然后迭代得到最后结果。我们维护的量res[i]是表示前i个数字有多少种解析的方式,接下来来想想递归式,有两种方式:第一种新加进来的数字不然就是自己比较表示一个字符,那么解析的方式有r

# Python 实现求和的各种方法
在编程中,求和是最基本的操作之一。在 Python 中,有多种方法可以实现不同的求和需求。本文将通过一个完整的示例来演示如何在 Python 中实现多个求和的方法,并为刚入行的小白们提供清晰的指导。
## 流程概述
在开始编写代码之前,我们先了解一下整体的流程。我们将使用表格来展示步骤。

有点意思的题目。用动态规划能够O(n)求解出来:a[i]代表子字符串string(0,i)的可能解码方式,a[i] = {a[i-1] or a[i-1]+a[i-2]}. 意思是假设string(i)不为0,至少a[i] == a[i-1],即一种解码方法是string{0,.....(i-1)}

regex的分组与捕获:分组就是用小括号(str)括起来的东西,就是一个分组。要想得到这些分组的信息,就要想办法捕获。每个分组都有编号,编号规则是从外向内,从左至右。 。例如,在表达式 (A)(B(C)) 中,存在四个这样的组: 0 (A)(B(C)) 1 (A) 2 (B(C)) 3 (C) 0表
