#include<stdio.h>

int main() {
	char s[3];
	int i,n = 0;
	scanf("%s",s);
	for (i = 0; i < 3; i++) {
		s[i] = 'a';
		n = n + 1;
	}
	for (i = 0; i < 3; i++) {
		s[i] = 'b';
		n = n + 2;
	}
	for (i = 0; i < 3; i++) {
		s[i] = 'c';
		n = n + 3;
	}
	if (n == 3)
		printf("Yes\n");
	else
		printf("No\n");
	return 0;
