class AtCoder
{
    static void Main()
    {
        string str;
        Boolean A=false ,B=false, C=false;
        str = Console.ReadLine();

        for(int i = 0 ; i < str.Length ; i++){
            if (str[i] == 'a')
                A = true;
            if (str[i] == 'b')
                B = true;
            if (str[i] == 'c')
                C = true;
        }

        if (A == true && B == true && C == true)
        {
            Console.WriteLine("Yes");
        }
        else
        {
