读懂题意以后还很容易做的, 和AbbottsRevenge类似加一个维度,筛子的形态,可以用上方的点数u和前面的点数f来表示,相对的面点数之和为7,可以预先存储u和f的对应右边的点数,点数转化就很容易了. 具体做法看代码 #include<bits/stdc++.h> using namespace std; ; ; int g[maxn][maxn]; bool vis[maxn][maxn][maxd][maxd]; struct State { int x,y,u,f,pre; }Q[]…

题目链接:uva 10837 - A Research Problem 题目大意:给定一个phin.要求一个最小的n.欧拉函数n等于phin 解题思路:欧拉函数性质有,p为素数的话有phip=p−1;假设p和q互质的话有phip∗q=phip∗phiq 然后依据这种性质,n=pk11(p1−1)∗pk22(p2−1)∗⋯∗pkii(pi−1),将全部的pi处理出来.暴力搜索维护最小值,尽管看上去复杂度很高,可是由于对于垒乘来说,增长很快,所以搜索范围大大被缩小了. #include <cstdi…
