using System;
class Product
{
	static void Main(string[] args)
	{
		string s = Console.ReadLine();
		bool[] b = new bool[3];
		for(int i = 0; i < s.Length; i++)
		{
			char c = s[i];
			b[0] |= c == 'a';
			b[1] |= c == 'b';
			b[2] |= c == 'c';
		}
		Console.WriteLine((b[0] && b[1] && b[2]) ? "Yes" : "No");
	}
