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

#include 

int main()
{
    int n, DIGITS = 3;
    char convert[] = "0123456789ABC";
    printf("#");

    for(int i = 0; i < DIGITS; i++)
    {
        scanf("%d", &n);
        printf("%c%c", convert[n / 13], convert[n % 13]);
    }
    return 0;
}
