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

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int main(){
	char str[150];
	int a[2];
	int n,i;
	while(scanf("%d",&n)!=EOF){
		getchar();
		memset(a,0,sizeof(a));
		for(i=0;i<n;i++){
			scanf("%c",&str[i]);
		}
		for(i=0;i<n;i++){
			if(str[i] == 'R'){
				a[0]++;
			}
			else{
				a[1]++;
			}
		}
		if(a[0]>a[1]){
			printf("Yes\n");
		}
		else{
			printf("No\n");
		}
	}
	return 0;
