using System;
class Program
{
	static void Main(string[] args)
	{
		// 整数の入力
		string s = Console.ReadLine();
        bool a = false;
        bool b = false;
        bool c = false;
        foreach(char d in s){
            if (d == 'a') a = true;
            if (d == 'b') b = true;
            if (d == 'c') c = true;
        }
        Console.WriteLine(a&&b&&c==true?"Yes":"No");
	}
