Given a Diameter D of circle and two points A and B are fixed at end of the diameter as shown in the figure. Figure
Sachin drew all distinct possible quadrilaterals with the following properties:
1. One of the diagonals is diameter AB (fixed)
2. Other two points lie on the circumference of the circle on opposite sides of AB.
3. All the sides have positive integral lengths.

Two quadrilaterals are said to be distinct if at least one of their vertices is not on the same point on the circumference of the circle.

Let A1,A2,B1,B2 be the areas formed between the quadrilateral and circle, as shown in the figure.

Your task is to find
1. Number of quadrilaterals L with A1+A2>B1+B2
2. Number of quadrilaterals E with A1+A2=B1+B2
3. Number of quadrilaterals R with A1+A2<B1+B2

Input Format

First line of the input consists of an integer T denoting the number of testcases. Each testcase consists of single integer D, diameter of circle.

Constraints

  • 1T20

  • 2D106

Output Format

For each of the testcases, output three space separated integers L,E,R.

Explanation

There are 4 possible quadrilaterals with sides in cyclic order starting from point A:
3 4 3 4
3 4 4 3
4 3 3 4
4 3 4 3

In all the cases A1+A2 and B1+B2 are equal hence answer is 0 4 0.
