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

Output


Y 67.985071301 1.014928699
Y 0.000000000 0.000000000
N
Y 2.000000000 2.000000000
Y 3.618033989 1.381966011

Y 998.998997995 1.001002005

Solution (in PYTHON3):

Solution:
n = int(input())
ans = [0,-1,-1,-1, 2 , 1.381966011]
for i in range(6, 1001):
    r=ans[i-1]
    l=r-0.2
    while (i - (i - l) * l > 0.00000001):
        tm = (r + l) / 2
        if (i - tm) * tm > i:
            r = tm
        else:
            l = tm
    ans.append(l)
for i in range(n):
    t = int(input())
    if ans[t]==-1:
        print('N')
    else:
        print('Y', t-ans[t], ans[t])
