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

#include<bits/stdc++.h>
using namespace std;
int main()
{
    string Table =  "0123456789ABCD";
    stack<char>ans[3];
    for (int i = 0; i < 3; i++)
    {
        int x; cin >> x;
        do
        {
            ans[i].push(Table[x % 13]);
            x = x / 13;
        } while (x);
    }
    cout << "#";
    for (int i = 0; i < 3; i++)
    {
        while (ans[i].size() < 2)
        {
            ans[i].push('0');
        }
        cout << ans[i].top(); ans[i].pop(); cout << ans[i].top();
    }
}
