Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
int main(){
	int a,b,c,i;
	a = b = c = 0;
	char s[4];
	scanf("%3s",s);
	for(i=0;i<3;i++){
		if(s[i]=='a') a=+1;
		if(s[i]=='b') b=+1;
		if(s[i]=='c') c=+1;
	}
	if(a == 1 && b == 1 && c == 1) printf("Yes\n");
	else printf("No\n");
