Solution (in CPP):

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