using namespace std;
typedef long long ll;
int main() {

priority_queue pq;
int Q,K;

cin>>Q>>K;

while(Q–)
{
int t;

   cin>>t;

   if(t == 1)
   {
     int x,y;

     cin>>x>>y;
     
     ll r = x*x + y*y;
     pq.push( r );

   }
   else if(t == 2)
   {
     while(pq.size()>K)
      pq.pop();

    if(pq.size() == K)
      cout<<pq.top()<<endl;
   }

}
return 0;
}

This code gets wrong-answer in TEST CASE 1.
Please tell me what is wrong in my code ?

You have declared x and y to be int.

And calculating the distance in long long. For you to get result in long long x and y also must be long long otherwise integer calculation is being performed.

Also declare pq as

priority_queue <ll> pq;
