Problem: Try guessing the statement from this picture: 

<image>

You are given a non-negative integer d. You have to find two non-negative real numbers a and b such that a + b = d and a ⋅ b = d.

Input

The first line contains t (1 ≤ t ≤ 10^3) — the number of test cases.

Each test case contains one integer d (0 ≤ d ≤ 10^3).

Output

For each test print one line.

If there is an answer for the i-th test, print "Y", and then the numbers a and b.

If there is no answer for the i-th test, print "N".

Your answer will be considered correct if |(a + b) - a ⋅ b| ≤ 10^{-6} and |(a + b) - d| ≤ 10^{-6}.

Example

Input

69
0
1
4
5
999
1000


Output


Y 67.985071301 1.014928699
Y 0.000000000 0.000000000
N
Y 2.000000000 2.000000000
Y 3.618033989 1.381966011
Y 997.998996990 1.001003010
Y 998.998997995 1.001002005

Solution (in JAVA):

Solution:
import java.util.Scanner;

public class Main {
	
	static int n;
	
	public static void main(String[] args) {
		
		Scanner scan = new Scanner(System.in);
		n  =scan.nextInt();
		
		for(int i = 0;i < n;i++){
			
			int d = scan.nextInt();
			
//			if(d==0){
//				
//				System.out.println("Y"+" "+"0.000000000"+" "+"0.000000000");
//				continue;			
//			}	
			if((d*d-4*d) < 0) System.out.println("N");
			else{
			
				System.out.println("Y"+" "+String.format("%.9f",(d+Math.sqrt(d*d-4*d))/2)+" "+String.format("%.9f",(d-Math.sqrt(d*d-4*d))/2));
							
			}		
		}		
	}
