Solution in C++14 (GCC 5.4.1) (judge verdict: Accepted)

#include <bits/stdc++.h>

using namespace std;

int main() {
  ios_base::sync_with_stdio(false);
  cin.tie(NULL);
  int N;
  cin >> N;

  int64_t result = 1;
  for (int i = 1; i <= 3; ++i) {
    result *= N;
  }

  cout << (result) << endl;
}
