      vector freqQuery(vector> queries) {

      vector v;

      map m;

      map m1;

      for (int i = 0; i 

      if (queries[i][0] == 1) {

  if (m[queries[i][1]] > 0) {

    m1[m[queries[i][1]]]--;

  }      

  m[queries[i][1]]++;

  m1[m[queries[i][1]]]++;

}

else if (queries[i][0] == 2) {

  if (m[queries[i][1]] > 0) {

    m1[m[queries[i][1]]]--;

    m[queries[i][1]]--;

    m1[m[queries[i][1]]]++;

  };

}

else {

  if (m1[queries[i][1]]>0)

    v.push_back(1);

  else 

    v.push_back(0);

}

      } return v; }
