Solution (in CPP):

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