There are N people numbered 1 to N. Each person wears a red hat or a blue hat.

You are given a string s representing the colors of the people. Person i wears a red hat if s_i is R, and a blue hat if s_i is B.

Determine if there are more people wearing a red hat than people wearing a blue hat.

Constraints

1 \leq N \leq 100

|s| = N

s_i is R or B.

Input

Input is given from Standard Input in the following format:

N
s

Output

Sample Output 1

Yes

There are three people wearing a red hat, and one person wearing a blue hat.

Since there are more people wearing a red hat than people wearing a blue hat, the answer is Yes.

Sample Input 2

    class MainClass
    {
        public static void Main(string[] args)
        {
            int input= Int32.Parse(Console.ReadLine());
            int N = input;
            string A = Console.ReadLine();
            string temp = "";
            string hoge = A;
            int a = hoge.Length;
            int Z = 0;
            for (int x = 0; x <= a - 1; x++)
            {
                temp = hoge.Substring(x, 1);
                if (temp == "R")
                    Z = Z + 1;
            }
            int L = N - Z;
            if (Z > L)
                Console.WriteLine("Yes");
            else
                Console.WriteLine("No");
