Problem Statement

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

If there are more people wearing a red hat than there are people wearing a blue hat, print Yes; otherwise, print No.

Sample Input 1

4
RRBR

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

No

There are two people wearing a red hat, and two people wearing a blue hat.

Since there are as many people wearing a red hat as people wearing a blue hat, the answer is No.

using System;
class Program
{
    static void Main(string[] args)
    {
        int Num = ReadInt();
        string RedBlue = Read();
        int RedCounter = 0;
        int BlueCounter = 0;

        for(int ii = 0; ii < Num; ii++)
        {
            if (RedBlue[ii].Equals("R"))
            {
                RedCounter = RedCounter + 1;
            }
            else
            {
                BlueCounter = BlueCounter + 1;
            }
        }

        if(RedCounter > BlueCounter)
        {
            Console.WriteLine("Yes");
        }
        else
        {
            Console.WriteLine("No");
        }
