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.
#include <stdio.h> #include <stdlib.h> #include <vector> using namespace std; void Show (int a); vector<int> mars; int main () { int red,green,blue; scanf("%d %d %d",&red,&green,&blue); int k=0; do { mars.push_back(blue%13); blue=blue/13; k++; }while( blue!=0); if( k==1) mars.push_back(0); k=0; do { mars.push_back(green%13); green=green/13; k++; }while( green!=0); if( k==1) mars.push_back(0); k=0; do { mars.push_back(red%13); red=red/13; k++; }while( red!=0); if( k==1) mars.push_back(0); printf("#"); for( k=5;k>=0;k--) Show(mars[k]); printf("\n"); system("pause"); return 0; } void Show (int a) { if( a<10) printf("%d",a); else printf("%c",'A'+a-10); }
