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

Output


Y 67.985071301 1.014928699
Y 0.000000000 0.000000000
N
Y 2.000000000 2.000000000

Y 997.998996990 1.001003010
Y 998.998997995 1.001002005

Solution (in PYTHON3):

Solution:
import math
t = int(input())
for tc in range(t):
    d = int(input())
    a = 1
    b = d
    c = d
    det = b**2 - 4*a*c
    if det == 0:
        root = b/(2*a)
        print( "Y %.9f %.9f"%( root, root))
    elif det < 0:
        print("N")
    else:
        root1 = -( -b + math.sqrt(det) ) / ( 2*a )
        root2 = -( -b - math.sqrt(det) ) / ( 2*a )
        print( "Y %.9f %.9f"%( root1, root2))
