The question

Give three numbers （ Decimal system ,0-168） Represents red, green and blue , Convert these three numbers into 13 Base number , If there is only one bit of a color, fill it 0 Complete to two .

Ideas

Hexadecimal conversion , Respectively for 13 Quotient and remainder , Finally, judge whether the result is two , Supplement if not 0, If the number in a bit exceeds ten, use ABC Instead of . Be careful 0.

Code

#include<stdio.h>

void function(int N,int b)
{
	if(N==0){
		printf("00");
	}else{
		int x[10],count=0,weight=1,sum=0;
		int flag=0;
		while(N){
			x[count++]=N%b;
			N/=b;
		}
		if(count==1){
			printf("0");
		}
		for(int i=count-1;i>=0;i--){
			if(x[i]>9){
				printf("%c",'A'+x[i]-10);
			}else{
				printf("%d",x[i]);
			}
		}
	}
}

int main()
{
	int R,G,B;
	scanf("%d%d%d",&R,&G,&B);
	printf("#");
	function(R,13);
	function(G,13);
	function(B,13);
	return 0;
