Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
void CyBerForCe() {
  long long n;
  cin >> n;
  long long ans = 0;
  if (n & 1) ans |= 16;
  if (n & 2) ans |= 2;
  if (n & 4) ans |= 8;
  if (n & 8) ans |= 4;
  if (n & 16) ans |= 1;
  if (n & 32) ans |= 32;
  cout << ans << "\n";
}
signed main() {
  ios_base::sync_with_stdio(0);
  cin.tie(0);
  cout.tie(0);
  CyBerForCe();
  return 0;
}
