Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int a, i = 0, temp;
  cin >> a;
  i += (a & 32);
  temp = a % 2;
  if (temp) i += 16;
  temp = a & 4;
  if (temp) i += 8;
  temp = a & 8;
  if (temp) i += 4;
  temp = a & 2;
  if (temp) i += 2;
  temp = a & 16;
  if (temp) i += 1;
  cout << i;
  return 0;
