Meme Problem
Try guessing the statement from this picture:
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}.
