### 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

### 代码

#include <iostream>
using namespace std;

int main() {
// 作为映射表
char c[14] = {"0123456789ABC"};
// cout << "#";
printf("#");
for(int i = 0; i < 3; ++i) {
int num;
// cin >> num;
scanf("%d", &num);
// 转成13进制，两位，高位是 / 13，地位是 % 13
cout << c[num / 13] << c[num % 13];
}
return 0;
}


Q.E.D.

Think twice, code once.
