In which particular line I am getting Runtime error ???
Problem code : GSUB (Practice)

Code:
#include<bits/stdc++.h>
using namespace std;

int main(){
ios_base::sync_with_stdio(false);
cin.tie(NULL);

int t=0,n=0,q=0;
int x=0,y=0,count = 0;
cin>>t;
cin>>n>>q;
vectorv(n+1,0);
while(t–){

  for(int i=0; i<n; i++)
    cin>>v[i];

for(int i=0; i<q; i++){
    cin>>x>>y;
    v[x-1] = y;
    for(int i = 0; i<n; i++){
        count++;
        if(v[i] == v[i+1])
            break;
    }
    cout<<count<<"\n";
    count = 0;
}

}
return 0;

}

You should have hyperlinked the problem Here. This line

should be inside the test case loop, that’s the first thing I see here. Try correcting it and check.
