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

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 9.2.1) (judge verdict: Accepted)

#include <stdio.h>

int main(void) {
	int N;
	char s[128] = "";
	int kitaeri = 0;
	int i;
	if (scanf("%d", &N) != 1) return 1;
	if (scanf("%127s", s) != 1) return 1;
	for (i = 0; i < N; i++) {
		if (s[i] == 'R') kitaeri++; else kitaeri--;
	}
	puts(kitaeri > 0 ? "Yes" : "No");
	return 0;
}
