Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int n, sol;
  cin >> n;
  if ((n & 1) != 0) sol += 16;
  if ((n & 2) != 0) sol += 2;
  if ((n & 4) != 0) sol += 8;
  if ((n & 8) != 0) sol += 4;
  if ((n & 16) != 0) sol += 1;
  if ((n & 32) != 0) sol += 32;
  cout << sol << '\n';
  return 0;
