Solution:
import java.util.*;

public class Codeforces {

  public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    
        int n = sc.nextInt();
        int[] digits = new int[6];
        for (int i = 0; i < 6; i++) {
            digits[i] = 1 & (n >> i);
        }
        
        int ans = 0;
        int[] perms = new int[] {
            4, 1, 3, 2, 0, 5
        };
        
        for (int i = 0; i < 6; i++) {
            ans |= (digits[i] << perms[i]);
        }
        
        System.out.println(ans);
    
  }
