People in Mars represent the colors in their computers in a similar way as the Earth people. That is, a color is represented by a 6-digit number, where the first 2 digits are for Red, the middle 2 digits for Green, and the last 2 digits for Blue. The only difference is that they use radix 13 (0-9 and A-C) instead of 16. Now given a color in three decimal numbers (each between 0 and 168), you are supposed to output their Mars RGB values.

Input

Each input file contains one test case which occupies a line containing the three decimal color values.

 

Output

For each test case you should output the Mars RGB value in the following format: first output "#", then followed by a 6-digit number where all the English characters must be upper-cased. If a single color is only 1-digit long, you must print a "0" to the left.

Sample Input

15 43 71

Sample Output

#123456

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner in=new Scanner(System.in);
		int n;
		String s="";
		for(int i=0;i<3;i++){
			n=in.nextInt();
			s=change(n)+s;
			//System.out.println(s);
		}
		s=s+"#";
		for(int i=s.length()-1;i>=0;i--){
			System.out.print(s.charAt(i));
		}
		System.out.println();
	}

	private static String change(int n) {
		if(n==0) return "00";
		String s="";
		int tmp;
		while(n!=0){
			tmp=n%13;
			if(tmp<10){
				s=s+tmp;
			}
			else{
				if(tmp==10) s=s+"A";
				if(tmp==11) s=s+"B";
				if(tmp==12) s=s+"C";
			}
			n=n/13;
			//System.out.println(tmp+" "+n+" "+s);
		}
		if(s.length()==1) s=s+"0";
		return s;
	}

}

　　注意点：当输入数字为0的时候，还有左补0
