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

Sample Solution：

#include <iostream>
using namespace std;

//计算题
int main(){
    int a,b,c;
    cin>>a>>b>>c;
    int w[6];
    string s="0123456789ABC";
    w[0]=a/13;
    w[1]=a%13;
    w[2]=b/13;
    w[3]=b%13;
    w[4]=c/13;
    w[5]=c%13;
    cout<<'#';
    for(int i=0;i<6;i++){
        printf("%c",s[w[i]]);
    }
    return 0;
}
