本文介绍了一个将十进制颜色值转换为火星RGB颜色值的方法，使用13进制而非常见的16进制来表示颜色。文章提供了一段C++代码实现，通过具体的输入输出样例展示了如何将三个十进制数值分别对应红绿蓝三通道的颜色值转换成火星RGB格式。

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

#include <iostream>
#include <string>
using namespace std;

string change(int n){
    if(n==0){
        return "00";
    }
    string s = "";
    while(n/13!=0 || n%13!=0){
        int temp = n%13;
        if(temp>9){
            if(temp==10){
                s = "A"+s;
            }
            if(temp==11){
                s = "B"+s;
            }
            if(temp==12){
                s = "C"+s;
            }
        }else{
            char tmp = '0'+temp;
            s = tmp + s;
        }
        n = n/13;
    }
    if(s.length()==1)
        s = "0"+s;
    return s;
}

int main()
{
    int a,b,c;
    string a1,b1,c1;
    cin>>a>>b>>c;
    a1 = change(a);
    b1 = change(b);
    c1 = change(c);
    cout<<"#"<<a1<<b1<<c1;
    return 0;
}
