Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int s[1000];
  int count = 0, n;
  cin >> n;
  while (n != 0) {
    s[++count] = n % 2;
    n = n / 2;
  }
  while (count <= 5) s[++count] = 0;
  swap(s[1], s[5]);
  swap(s[3], s[4]);
  int num = 0;
  int p = 1;
  for (int i = 1; i <= count; i++) {
    num += p * s[i];
    p = p * 2;
  }
  cout << num << endl;
  return 0;
}
