Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  ios_base::sync_with_stdio(false);
  cin.tie(NULL);
  int n, x = 0;
  cin >> n;
  if (n & 1) x += 16;
  if (n & 2) x += 2;
  if (n & 4) x += 8;
  if (n & 8) x += 4;
  if (n & 16) x += 1;
  if (n & 32) x += 32;
  cout << x;
  return 0;
