Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
using ll = long long;
using ii = pair<int, int>;
int main() {
  ios::sync_with_stdio(0);
  cin.tie(0);
  int x;
  cin >> x;
  string bin = bitset<64>(x).to_string();
  reverse((bin).begin(), (bin).end());
  swap(bin[0], bin[4]);
  swap(bin[2], bin[3]);
  ll ans = 0;
  ll po = 1;
  for (int i = 0; i < 64; ++i) {
    ans += ((bin[i] == '1') * po);
    po *= 2LL;
  }
  cout << ans << '\n';
  return 0;
}
