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 簡單題： #include <iostream> #include <string.h> #include <stdlib.h> #include <stdio.h> #include <math.h> #include <algorithm> #include <vector>using namespace std; int a,b,c; char aa[14]={'0','1','2','3','4','5','6','7','8','9','A','B','C','D'}; void dfs(int x,int cnt) {if(x<13){if(cnt==0)printf("0");printf("%c",aa[x]);return;}dfs(x/13,cnt+1);printf("%c",aa[x%13]); } int main() {scanf("%d%d%d",&a,&b,&c);printf("#");dfs(a,0);dfs(b,0);dfs(c,0);printf("\n");return 0; }
