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.

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: Wrong Answer)

#include<stdio.h>
#include<stdlib.h>
int main() {
	int i, j, k, f = 0, n, t, m, a, b, c;
	char x;
	a = 0;
	b = 0;
	scanf("%d", &n);
	for (i = 0;i < n;i++) {
		scanf("%c", &x);
		if (x == 'R') {
			a = a + 1;
		}
		else {
			b = b + 1;
		}
	}
	if (a > b) {
		printf("Yes");
	}
	else {
		printf("No");
	}

	return 0;
