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

提交代码

题目意思：给你三个十进制数，转化为十三进制输出。

解题思路：

168小于13的平方，所有最多只有两位。组成为（num/13）（num%13）

注意：char str[14] = {'0,','1','2','3','4','5','6','7','8','9','A','B','C'};会有几个点过不去

#include<stdio.h>char str[14] = {"0123456789ABC"};int main(){int a,b,c;//freopen("input.txt","r",stdin);scanf("%d%d%d",&a,&b,&c);printf("#");printf("%c%c",str[a/13],str[a%13]); printf("%c%c",str[b/13],str[b%13]);printf("%c%c\n",str[c/13],str[c%13]);return 0;}
