#include <bits/stdc++.h>
using namespace std;
int main()
{

  int m;cin>>m;
  while(m--)
  {
    string op;cin>>op;
    if(op=="IN")
    {
      string name,pos;
      cin>>name>>pos;
      if(pos=="V")
      {
        V.push(name);
      }
      else
      {
        N.push(name);
      }
    }
    else
    {
      string pos;
      cin>>pos;
      if(pos=="V")

      N.pop();
