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 , the middle 2 digits for , and the last 2 digits for . 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. Red Green Blue

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 to its left. # 0

Sample Input:

15 43 71

Sample Output:

#123456

题目大概是啥意思呢

给你三个数字。 15 43 71

把这三个数字变成13进制的数字。就变成了12 34 56

13个数分别是1 2 3 4 5 6 7 8 9 A B C

如果不足13,那么起码也要补足两位,比如10就是 0A. 8就是08

但他们是挨在一块的.就比如上面的15 43 71 就变成了123456,前面还得加个#

主要就是进制转换问题。

#include <bits/stdc++.h>
using namespace std;
int main()
{
    int r,g,b;
    char num[13] = {'0','1','2','3','4','5','6','7','8','9','A','B','C'};
    scanf("%d%d%d",&r,&g,&b);
    printf("#");
    cout<<num[r/13]<<num[r%13]<<num[g/13]<<num[g%13]<<num[b/13]<<num[b%13];
}
