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}.

Example

Input

Output


Y 67.985071301 1.014928699
Y 0.000000000 0.000000000
N
Y 2.000000000 2.000000000
Y 3.618033989 1.381966011
Y 997.998996990 1.001003010
Y 998.998997995 1.001002005

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
const long long INF = 1e18;
using namespace std;
int main() {
  ios::sync_with_stdio(0);
  cin.tie(0);
  int tt;
  cin >> tt;
  while (tt--) {
    double d;
    cin >> d;
    if (d * d - 4 * d >= 0) {
      double r1 = (d + sqrt(d * d - 4 * d)) / (2.0);
      double r2 = (d - sqrt(d * d - 4 * d)) / (2.0);
      if (r1 >= 0 && r2 >= 0)
        cout << "Y " << setprecision(9) << fixed << r1 << " " << r2 << "\n";
      else
        cout << "N"
             << "\n";
    } else {
      cout << "N"
           << "\n";
    }
