Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int a;
  cin >> a;
  int b[8], j = 5;
  memset(b, 0, sizeof(b));
  while (a != 0) {
    b[j--] = a % 2;
    a /= 2;
  }
  swap(b[1], b[5]);
  swap(b[2], b[3]);
  int ans = 0;
  for (int i = 5, j = 0; i >= 0; i--, j++) ans += (b[i] * pow(2, j));
  cout << ans << endl;
  return 0;
}
