Induction of Design Pattern
网上查到的设计模式有23种，通过归纳去认识他们也是一种不错的视角。 我这边不按照主流的观点去划分为创建型、结构型、行为型三大类，我只归纳为创建型（Creational Class）、简单功能场景（Simple Method Class）、复杂功能场景（Complex Method Class）三大类 ......
# Codeforces Round 887 E Ina of the Mountain（反悔贪心）

点击提交按钮的时候，直接服务器端报上面的错，意思是json不能解析。 因为程序中用到了递归，就是自己引用了自己（实体类）。 原因： 实体类中children定义的是对象的形式，但是前端定义的是数组[]的形式。 解决： 前端改成对象形式，{}，这样前后端一致就可以正常传值了。 上面children赋值 ......
【题解】CF1852C Ina of the Mountain
我们先从题目的一部分入手。 如果说，我们没有当一个数为 $0$ 时，让这个数变成 $k$ 的性质，我们如何求答案呢？ 很简单，在图上就是： 绿色线段的长度加起来即为答案（本图中是 $6$） 我们考虑很显然地，将一个数从 $0$ 变为 $k$ 即为将一个数一开始加上 $k$ 我们如果要让第 $i$ 列 ......
