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

#include<cstdio>

int r,g,b;

void change(int n){
    int a=n/13;
    int b=n%13;
    if(a>=10){
        char c='A'+a-10;
        printf("%c",c);
    }else{
        printf("%d",a);
    }
    if(b>=10){
        char c='A'+b-10;
        printf("%c",c);
    }else printf("%d",b);
}
int main(){
    scanf("%d %d %d",&r,&g,&b);
    printf("#");
    change(r);
    change(g);
    change(b);
    return 0;
}
