哈哈我也一样
```cpp
#include<iostream>
#include<cstdio>
#include<algorithm>
using namespace std;
#define LL long long int
LL a,b,ans;
int main(){
//freopen("zouyudong.in","r",stdin);
//freopen("zouyudong.out","w",stdout);
scanf("%ld%ld",&a,&b);
ans=b+1;
for(LL i=0;;i++){
if(ans%a==0){
printf("%ld",ans/a);
break;
}
ans+=b;
}
return 0;
}
```

加一
```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
int a,b,ans=1;
cin>>a>>b;
while((a*ans)%b!=1)
{
ans++;
}
cout<<ans;
return 0;
}
```

violet++;
```cpp
#include<stdio.h>
int main()
{
long long int a,b;
scanf("%lld%lld",&a,&b);
long long int qaq=a%b;
long long int count=0;
long long int sum=0;
for(;sum!=b+1;sum+=qaq,count++)
{
if(sum>b+1)
sum-=b;
}
printf("%lld",count);
return 0;
}
```
