using namespace std;

int main() {
   int n;
   cin >> n;
   vector<int> aa(3);
   for (int i = 0; i < 100 / 5; i++){
    for (int j = 0; j < 100 / 3; j++){
        int last = 100 - 5 * i - 3 * j;
        if(last > 0){
            int k = 3 * last;
            if( i + k + j == 100)
            cout << i << " " << j << " " << k << endl;
        }
    }
   }
