#include <bits/stdc++.h>
#define REP(i, n) for(int i = 0; i < n; i++)
using namespace std;
typedef long long ll;

#define array_sort_asc(array,size) sort(array, array+size);
#define array_sort_desc(array,size) sort(array, array+size,greater<>());

int main() {
    int n;
    cin >> n;

    cout << pow(n,3) << endl;
}
