Problem E
Mandelbrot

Born in Warsaw, Benoît Mandelbrot (1924–2010) is considered the father of fractal geometry. He studied mathematical processes that described self-similar and natural shapes known as fractals. Perhaps his most well-known contribution is the Mandelbrot set, which is pictured below (the set contains the black points):

The Mandelbrot set is typically drawn on the complex plane, a 2-dimensional plane representing all complex numbers. The horizontal axis represents the real portion of the number, and the vertical axis represents the imaginary portion. A complex number c=x+yi (at position (x,y) on the complex plane) is not in the Mandelbrot set if the following sequence diverges:

zn+1zn2+c

beginning with z0=0. That is, limn|zn|=. If the sequence does not diverge, then c is in the set.

Recall the following facts about imaginary numbers and their arithmetic:

i=1,i2=1,(x+yi)2=x2y2+2xyi,|x+yi|=x2+y2

where x and y are real numbers, and || is known as the modulus of a complex number (in the complex plane, the modulus of x+yi is equal to the straight-line distance from the origin to the the point (x,y)).

Write a program which determines if the sequence zn diverges for a given value c within a fixed number of iterations. That is, is c in the Mandelbrot set or not? To detect divergence, just check to see if |zn|>2 for any zn that we compute – if this happens, the sequence is guaranteed to diverge.

Input

There are up to 15 test cases, one per line, up to end of file. Each test case is described by a single line containing three numbers: two real numbers 3x,y3, and an integer 0r10000. Each real number has at most 4 digits after the decimal point. The value of c for this case is x+yi, and r is the maximum number of iterations to compute.

Output

For each case, display the case number followed by whether the given c is in the Mandelbrot set, using IN or OUT.
