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
t = int(input())
for i in range(t):
    d = int(input())
    if d == 0:
        print("Y 0 0")
    elif d < 4:
        print("N")
    else:
        delta = d*d-4*d
        a1 = (d+sqrt(delta))/2
        a2 = (d-sqrt(delta))/2
        b1 = d - a1
        b2 = d - a2
        if a1 >= 0 and b1 >= 0:
            print("Y", end=' ')
            print(a1, end=' ')
            print(b1)
        elif a2 >= 0 and b2 >= 0:
            print("Y", end=' ')
            print(a2, end=' ')
            print(b2)
        else:
            print("N")
