SP334 PHDISP - The Philosophical Dispute

One day, mathematician and philosopher were engaged in a heated dispute. Philosopher said: \- Ideal line has only length and no width, therefore, no line can have an area. Mathematician replied: \- That's as it may be, but still you can ll a square with a line in such a way that there will be no gaps. And you can't deny that a square has an area, and he grinned. But Philosopher still wasn't convinced: \- Show me this line, then. \- With pleasure... - responded Mathematician and scribbled some equations on a piece of paper:  \- With t increasing, the point $(x, y)$ will move around the square, forming a line. \- So what? - asked Philosopher. How is it going to ll the entire square? \- Indeed, it will, - said Mathematician, - Whichever point inside the square you draw, the line will eventually cross that point. \- No, - replied Philosopher indignantly, - Anyway, I don't believe. When will the line cross this point? - and he put a thick dot inside the square. Give Philosopher an answer.

$t$ – number of tests \[$t \le 150$\], than t test cases follows. The first line of each test case contains the coordinates $(x0, y0)$ of the dot center $(-1 \le x_0, y_0 \le 1)$. The second line contains $eps \le 0.0001$ - the radius of the dot (the dot is essentially a small circle).

For each test case output any value of t in the segment $[0, 10^{12}]$, which corresponds to the line crossing the dot, or "FAIL", if the line doesn't cross the dot.
