1027 Colors in Mars（20分）

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 #include<bits/stdc++.h>
 2 using namespace std;
 3 char digit[]={'0','1','2','3','4','5','6','7','8','9','A','B','C'};
 4 void to13(int x){
 5     int a[10]={0};
 6     int i=0;
 7     while(x){
 8       a[i++]=x%13;
 9       x/=13;
10     }
11     cout<<digit[a[1]]<<digit[a[0]];
12 }
13 int main(){
14     int r,g,b;
15     cin>>r>>g>>b;
16     cout<<'#';
17     to13(r);
18     to13(g);
19     to13(b);
20 }
