Don't use a package, use class Main.
Check input and AC output for thousands of problems on uDebug!

why i get RTE ????

Code: Select all

``````#include<iostream>
#include<vector>
#include<iterator>
using namespace std;
vector<int>vi[100050];
vector<int>::iterator it;
int main()
{

int i,j,m,n,u,v,a;
while(cin>>m>>n)
{
for(i=1;i<=m;i++)
{
cin>>a;
vi[a].push_back(i);
}

for(j=1;j<=n;j++)
{
cin>>u>>v;
it=vi[v].begin();
if(u>vi[v].size())
{
cout<<0<<endl;
}

else{
int k=1;
while(it!=vi[v].end()){
if(k==u){
cout<<*it<<endl;
break;
}
it++;
k++;
}
k=0;
}
}

for(int l=0;l<=100000;l++)
vi[l].clear();

}
return 0;
}
