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
a = []
for i in range(int(input())):
    a.append(int(input()))
for i in a:
    s = i * i - i * 4
    if s < 0:
        print("N")
    else:
        n = round((i * 1 + math.sqrt(s))/2,9)
        m = round((i * 1 - math.sqrt(s))/2,9)
        ln = len(str(n).split(".")[1])
        lm = len(str(m).split(".")[1])
        print("Y",str(n) + ("0" * (9 - ln)),str(m) + ("0" * (9 - lm)))
