#include<iostream>
using namespace std;

int main()
{
	int a = 0, b = 0, c = 0;
	string s;
	cin >> s;
	for (int i = 0; i < 3; i++) {
		if (s[i] == 'a') {
			a++;
		}
		else if (s[i] == 'b') {
			b++;
		}
		else {
			c++;
		}
	}
	if (a == 1 && b == 1 && c == 1) {
		cout << "Yes";
	}
	else {
		cout << "No";
	}
	return 0;
