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:
from math import sqrt
for _ in range(int(input())):
    d=int(input())
    if d**2<4*d:
        print("N")
    else:
        a=(-d+sqrt(d**2-4*d))/2
        a_=d-a
        b=(-d-sqrt(d**2-4*d))/2
        b_=d-b
        # print(a,a_,b,b_)
        # if a<0 and b<0:
        #     print("N")
        # else:
        print("Y "+str(abs(a))+" "+str(abs(b)))
