Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int32_t main() {
  ios_base::sync_with_stdio(false);
  cin.tie(0);
  cout.tie(0);
  ;
  int n;
  cin >> n;
  bitset<6> a(n);
  string s = a.to_string();
  swap(s[1], s[5]);
  swap(s[2], s[3]);
  bitset<6> b(s);
  cout << static_cast<int>(b.to_ulong()) << "\n";
}
