  • Performs “while” loop. This loop will perform upto “numbers” equal to “-1”.
    • In this loop, first read the number from user.
    • If the number is not equal to “-1”, then check if the number is in map or not using “find” function.
      • If it is, then assign “mapResult[numbers]” is “1”.
      • Otherwise, increment the counter
  • Declare constant iter “result” in “map” template class.
  • Display the given result using “for” loop.
