Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int a;
  cin >> a;
  string s;
  while (a) {
    s += (a & 1) + '0';
    a >>= 1;
  }
  while (s.size() < 6) s += '0';
  reverse(s.begin(), s.end());
  swap(s[1], s[5]);
  swap(s[2], s[3]);
  int ans = 0;
  for (int i = 0; i < 6; i++) {
    ans = ans * 2 + (s[i] - '0');
  }
  cout << ans << endl;
  return 0;
}
