单机通过，不能AC

import java.util.Scanner;

public class Main {
	@SuppressWarnings("resource")
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		int nextInt = in.nextInt();
		int num = 0;
		int i = 0;
		while (nextInt!=0) {
			num += nextInt%8*Math.pow(10, i);
			nextInt /=8;
			i++;
		}
		System.out.println(num);
	}
}
