思路: 找每一个数的循环节,注意优化!! 每次找一个数的循环节时,记录其路径,下次对应的数就不用再找了…… 代码如下: #include<iostream> #include<cstdio> #include<stack> #include<cstring> #define ll __int64 using namespace std; ],to[],an[]; stack<int>p; ll gcd(ll a,ll b) { if(a<b…

首先将扑克牌进行一次置换,然后分解出所有的循环节,所有循环节的扑克牌个数的最小公倍数即为答案 #include <stdio.h> #include <string.h> #include <algorithm> using namespace std; #define LL long long int n,k; LL d[850],ct; int vis[850]; int a[850]; int dfs(int x) { if(!vis[a[x]]) { ct++;…
