## 1027 Colors in Mars ##

### 0、题目 ###

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 Specification: ####

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

#### Output Specification: ####

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 its left.

#### Sample Input: ####

15 43 71

#### Sample Output: ####

#123456

### 1、大致题意 ###

给三个十进制的数，把它们转换为十三进制的数输出。要求在前面加上一个"\#"号

### 2、基本思路 ###

因为 `0~168` 的十进制转换为 `13进制` 不会超过两位数，所以这个两位数为  ( n u m / 13 ) (num / 13) (num/13) 、  ( n u m % 13 ) (num \\% 13) (num%13) 构成的数字

### 3、AC代码 ###

#include <cstdio>
    using namespace std;
    int main() {
        
        char c[14] = {
        "0123456789ABC"};
        printf("#");
        for(int i = 0; i < 3; i++) {
        
            int num;
            scanf("%d", &num);
            printf("%c%c", c[num/13], c[num%13]);
        }
        return 0;
    }
