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}.

Solution (in PYTHON3):

Solution:
import math as mt
t=int(input())
#t=1
for _ in range(t):
    d=int(input())
    #l=list(map(int,input().split()))
    if d**2 -4*d<0:
        print('N')
    else:    
        x1=(d+mt.sqrt(d**2 - 4*d))/2
        x2=(d-mt.sqrt(d**2 - 4*d))/2
        if d-x1>=0 and  x1>=0:
            
            print("Y",d-x1,x1)
        elif d-x2>=0 and  x2>=0:
            print("Y",d-x2,x2)
        else:
            print("N")
