求助，wa了几个点```cpp
#include <bits/stdc++.h>
using namespace std;
int n;
int f[210086]={};
int main() {
cin>>n;
for(int i=0;i<n;i++){
cin>>f[i];
}
int c=0,t=-1;
bool end=1;
int s=n;
while(c<s){
t=-1;
end=0;
for(int i=0;i<n;i++){
if(f[i]!=t){
if(f[i]!=-1){
cout<<i+1<<" ";
end=1;
t=f[i];
}
f[i]=-1;
c++;
}else{
s++;
continue;
}
}
if(end){
cout<<endl;
}else{
return 0;
}
}
return 0;
}
