Solution (in JAVA):

Solution:
import java.util.Scanner;

public class Main
{
    public static void main(String[] args)
    {
        Scanner sc = new Scanner(System.in);

        int num = sc.nextInt();

        String binary = Integer.toBinaryString(num);

        if(binary.length() < 6)
        {
            int len = binary.length();

            for(int i=0; i<6-len; i++)
            {
                binary = "0" + binary;
            }
        }

        String stringBuilder = String.valueOf(binary.charAt(0)) +
                binary.charAt(5) +
                binary.charAt(3) +
                binary.charAt(2) +
                binary.charAt(4) +
                binary.charAt(1);
        
        System.out.println(Integer.parseInt(stringBuilder, 2));
    }
