Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  ios_base::sync_with_stdio(false);
  cin.tie(0);
  cout.tie(0);
  int order[] = {4, 1, 3, 2, 0, 5}, n;
  cin >> n;
  int ans = 0;
  int i = 0;
  while (i <= 5) {
    if (n >> i & 1) {
      int x = 1 << order[i];
      ans = x | ans;
    }
    i++;
  }
  cout << ans;
}
