@[_prayer](/user/273716) AC 了
你把 a[0] 设置为 0
```
#include <iostream>
using namespace std;
int main() {
int n,m,i,cnt=0;
cin>>n>>m;
int a[n+1];
for(i=1;i<=n;i++){
a[i]=1;
}
a[0] = 0;//
i=1;
int k=1;
while(cnt!=n){
if(a[i%(n+1)]==1){
if(k==m){
cnt++;
a[i%(n+1)]=0;
k=0;
cout<<i%(n+1)<<" ";
}
k++;
}
i++;
}
return 0;
}
```
