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
简析：主要是给三个10进制数，然后转化成13进制数，考虑到的数在0~168之间，就直接除和取余再输出就可以啦。
#include<iostream>
using namespace std;
int main()
{
char num[13] = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C'};
int a, b, c;
cin>>a>>b>>c;
cout << '#';
cout << num[a / 13] << num[a % 13] << num[b / 13] << num[b % 13] << num[c / 13] << num[c % 13];
return 0;
}
