На различни компилатори ми излиза различно... Има ли някой който да е решил задачата? Благодаря предварително!

#include <iostream>
#include <string>
using namespace std;

int main() {

  int width, length, height;
  cin >> width >> length >> height;
  int totalSpace = width * length * height;

  int totalBoxes;
  int box;
  string input;

  cin >> input;
  
  while(input != "Done") {
  
    box = stoi(input);
    totalBoxes += box;

    if (totalSpace < totalBoxes) { break; }
    cin >> input;  

  }

  if (totalSpace < totalBoxes) {
    int res = totalBoxes - totalSpace;
    cout << "No more free space! You need " << res << " Cubic meters more." << endl;
  } else {
    int res = totalSpace - totalBoxes;
    cout << res << " Cubic meters left." << endl;
  }

  return 0;

}
