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 \(a \cdot b = d\).
The first line contains \(t\) (\(1 \le t \le 10^3\)) — the number of test cases.Each test case contains one integer \(d\) \((0 \le d \le 10^3)\).
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 \(|(a + b) - a \cdot b| \le 10^{-6}\) and \(|(a + b) - d| \le 10^{-6}\).
