#include <bits/stdc++.h>

#ifndef DEBUG

#define REP(t,i,a,b) for(t i = a; i < b; ++i)

typedef long long ll;

using std::cin;
using std::cout;
using std::endl;
using std::vector;

int main (void) {
    std::cin.tie(nullptr);
    std::ios::sync_with_stdio(false);
    int n;
    cin >> n;
    cout << n*n*n << endl; 
    return 0;
