此题是一道线段树的裸题,这里只是为了保存我的zkw线段树模板 #include <cstdio> #include <cstring> #include <iostream> using namespace std; typedef long long LL; inline int geti() { static int Ina; static char Inc; static bool InSign; InSign = false; while ((Inc = get…

A Simple Problem with Integers 这个题目首先要打表找规律,这个对2018取模最后都会进入一个循环节,这个循环节的打表要用到龟兔赛跑. 龟兔赛跑算法 floyed判环算法 这个算法我觉得还是很有意思的,可以学习一下. 不过这个题目这个算法打表还是有点难写的. 由这个算法可以得到这个循环节的最大长度是6 最大入环距离是4. 为什么有些循环节不是6,还是可以用6呢,因为每个元素平方最大周期为6,且6是其他所有周期的公倍数. 然后学完之后还是不太会这个题目怎么写,2018…
