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

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

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.

Solution in JavaScript (node.js v5.12) (judge verdict: Runtime Error)

function RorB(input){
  let R=0,B=0;
  const inputN = input.split('\n');
  N = parseInt(inputN[0].replace(/\r?\n/g,''));
  inputS = inputN[1].replace(/\r?\n/g,'').split('');
  inputS.forEach((s)=>{
    if (s === 'R'){
      R++;
    }else{
      B++;
    }
  });
  if (R > B){
    console.log("Yes");
  } else {
    console.log("No");
  }
}

RorB(require("fs").readFileSync("/dev/stdin", "utf8"));
