真的没有别的办法了吗
by 黄油猫发电厂 @ 2019-02-16 12:02:45
当然有别的办法，开$unsigned-long-long$， 用取模%(mod)运算，避免了溢出和超时，什么LE通统没有的
```cpp
#include<bits/stdc++.h>
using namespace std;
unsigned long long x,y,po=0;
int main(){
cin>>x>>y;
if(y>x)swap(y,x);
while(x%y!=0){
po+=x/y*y*4;
x%=y;
if(y>x)swap(y,x);
}
po+=x*4;
cout<<po<<endl;
return 0;
}
//亲测AC100分！！
```
不过大家还是自己写代码的好 ~~抄一下也无伤大雅~~
