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
这道题考察了进制转换,因为只有两位数,所以我们的方式处理比较简单
#include <iostream> using namespace std; int main() { int a, b, c; char ch[] = "0123456789ABC"; scanf("%d%d%d", &a, &b, &c); printf("#%c%c%c%c%c%c", ch[a/13], ch[a%13], ch[b/13], ch[b%13], ch[c/13], ch[c%13]); return 0; }
