Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int factors[1010 + 10];
int main() {
  int n;
  cin >> n;
  int a[10];
  for (int i = 0; i < 6; i++) {
    a[i] = n % 2;
    n >>= 1;
  }
  swap(a[0], a[4]);
  swap(a[2], a[3]);
  int res = 0;
  for (int i = 0, pow = 1; i < 6; i++) {
    res += a[i] * pow;
    pow <<= 1;
  }
  cout << res << endl;
}
