嗯...这篇题解写的原因是一位大佬网友问我的题 本蒟蒻为了纪念下这一刻,就写了 我只会写一写基本思路,经不起推敲 还是大家凑活看吧 重点来了 在bfs时,队列里的每个元素由一个高精度的数和那个数模m的值 拓展节点时如果拓展得到的余数为零,直接返回输出即可 要是这个余数不为零且之前没有出现过,就加入队列,之前出现过,就舍弃 这就是我的思路,再附上Code #include<bits/stdc++.h> #define LL long long int using namespace std; ,

方法一:辗转相除法(欧几里得 Euclidean) 用“较大数”除以“较小数”,再用较小数除以第一余数,再用第一余数除以第二余数: 反复直到余数为零为止. #include<iostream> #include<algorithm> using namespace std; /*其计算原理依赖于下面的定理: 定理:gcd(a,b) = gcd(b,a mod b) 证明:a可以表示成a = kb + r,则r = a mod b 假设d是a,b的一个公约数,则有 d|a, d|b,
