题目链接 题意 : 就是把n个数安排在环上,要求每两个相邻的数之和一定是素数,第一个数一定是1.输出所有可能的排列. 思路 : 先打个素数表.然后循环去搜..... #include <cstdio> #include <cstring> #include <iostream> using namespace std ; ]; ] ,cs[]; int n ; void get_prime() { memset(prime,,sizeof(prime)); prime[…

在刚刚写完代码的时候才发现我以前交过这道题,可是没有过. 后来因为不理解代码,于是也就不了了之了. 可说呢,那时的我哪知道什么DFS深搜的东西啊,而且对递归的理解也很肤浅. 这道题应该算HDU 2610 Sequence one的简化版,判重也非常简单. 其他也没有什么好说的了,直接上代码吧. //#define LOCAL #include <iostream> #include <cstdio> #include <cstring> #include <cma…
