原题传送门 题意:给定n(n≤106)个数,要求将它化为混偱环小数的形式,即前k个数不参与循环,之后所有数以p为循环节长度进行循环.求k和p,要求k+p尽量小,k+p相等时要求p尽量小. 样例1 输入: 6 612534 3157 423 3157 423 3157输出: 1 2 样例2 输入: 9  1 2 1 3 1 2 1 3 1输出: 0 4 分析:想了两个晚上,没有想到有什么数据结构可以支持这种操作,想要二分答案又不满足单调性,于是去请教TJW,TJW一语点醒梦中人:(还是log n的…

以前我还是写过KMP的文章的 现在我们可以求一下循环节啊 Slot Machines Gym - 101667I #include<bits/stdc++.h> using namespace std; ; int a[N],f[N],n; int main() { scanf("%d",&n); ; i<n; i++) scanf(]); f[]=-; ,j=-; i<n; i++,j++) { &&a[j]!=a[i])j=f[j];…

A:Broadcast Stations 留坑. B:Connect3 题意:四个栈,每次放棋子只能放某个栈的栈顶,栈满不能放,现在给出(1, x) 表示黑子放在第x个栈的第一个位置,白子放在第b个栈的第a个位置并且是胜利局势的情况有几种,只要有三个相同的连在一起就是赢了 思路:数据很小,暴力搜索即可,注意判重. #include <bits/stdc++.h> using namespace std; int x, a, b; ][]; // 0 not done // 1 white //…

2017 ACM ICPC Asia Regional - Daejeon Problem A Broadcast Stations 题目描述:给出一棵树,每一个点有一个辐射距离\(p_i\)(待确定),但\(p_i==0\)的点不能辐射自己,只能由别的点辐射覆盖.求\(p_i\)的和的最小值. Problem B Connect3 题目描述:有一个\(4 \times 4\)的网格,两个人玩游戏,第一个人用黑棋,第二人用白棋.每次选择一列,将棋子扔下去,直到最下一个空的格子.现在给出第一个人下…

题目传送门 只打了三个小时. A. Broadcast Stations B. Connect3 补题:zz 题解:因为格子是4*4的,而且每次落子的位置最多是只有四个,再加上剪枝,情况不会很多,直接爆搜就行了,再用三进制记录已经合法的情况,去掉重复的情况就行了.(用vs2017交会ac,但c++17会wa1,很奇怪) //#pragma comment(linker, "/STACK:102400000,102400000") #include<iostream> #in…
