给定三个10进制、都不超168的整数,将仨个数都转为13进制数一并输出。

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

思路一:
问题的实质,是十分简单的进制转换(10转13),稍微注意输出时把大于9的数转要求的大写字母就好了。
#include <iostream>
#include <cstring>
using namespace std;
char get(int a){ //统一处理为字符输出
if(a>9) return a-10+'A'; //超9的话先减10再转 大写字母字符
else return a+'0'; //9以内的话转 数字字符
}
int main(){
int a[3];
for(int i=0;i<3;i++) cin>>a[i];
cout<<'#';
for(int i=0;i<3;i++) cout<<get(a[i]/13)<<get(a[i]%13);
return 0;
}
