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


7
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 PYTHON3):

Solution:
T = int(input())
for _ in range(T):
	d = int(input())
	if d == 0:
		print('Y 0.000000000 0.000000000')
	elif d < 4:
		print('N')
	else:
		a = (d+(((d**2)-(4*d))**(0.5)))/2
		b = (d-(((d**2)-(4*d))**(0.5)))/2
		if a>=0 and b>=0:
			print(f'Y {a:.9f} {b:.9f}')
		else:
			print('N')
