Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int n;
  cin >> n;
  int perm[] = {5, 0, 2, 3, 1, 4};
  int ans = 0;
  for (int i = 0; i < 6; i++) {
    int cur = (n & (1 << perm[i])) != 0;
    ans = (ans << 1) | cur;
  }
  cout << ans << '\n';
  return 0;
}
