1027. Colors in Mars (20)

标签：c++   pat   

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.

#123456

#include <iostream>
using namespace std;

void etom(int num) {
    char m[2] = {'0', '0'};
    char n[13] = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C'};
    m[1] = n[num % 13];
    m[0] = n[num / 13];
    cout<<m[0]<<m[1];
}
int main() {
    int r, g, b;
    while(cin>>r>>g>>b) {
        cout<<"#";
        etom(r);
        etom(g);
        etom(b);
        cout<<endl;
    }
    return 0;
}
