1027. Colors in Mars (20)
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.
Sample Input
15 43 71
Sample Output
#123456
题目大意:就是将十进制数换成13进制数,如果有字母就用大写的A、B、C来表示;
#include<iostream> #include<cstdio> #include<cstring> using namespace std; int main(){ int n,m; string str[14]={"0","1","2","3","4","5","6","7","8","9","A","B","C"}; int i,j,k; for(i=0;i<3;i++){ scanf("%d",&n); m=n%13; n=n/13; if(n==0){ if(i==0){ cout<<"#"; } cout<<"0"<<str[m]; } else{ if(i==0){ cout<<"#"; } cout<<str[n]<<str[m]; } } cout<<endl; return 0; }
