Intersecting Lines 

We all know that a pair of distinct points on a plane defines a line and that a pair of lines on a plane will intersect in one of three ways: 1) no intersection because they are parallel, 2) intersect in a line because they are on top of one another (i.e. they are the same line), 3) intersect in a point. In this problem you will use your algebraic knowledge to create a program that determines how and where two lines intersect.

Your program will repeatedly read in four points that define two lines in the x-y plane and determine how and where the lines intersect. All numbers required by this problem will be reasonable, say between -1000 and 1000.

Input

The first line contains an integer N between 1 and 10 describing how many pairs of lines are represented. The next N lines will each contain eight integers. These integers represent the coordinates of four points on the plane in the order tex2html_wrap_inline35 . Thus each of these input lines represents two lines on the plane: the line through tex2html_wrap_inline37 and tex2html_wrap_inline39 and the line through tex2html_wrap_inline41 and tex2html_wrap_inline43 . The point tex2html_wrap_inline37 is always distinct from tex2html_wrap_inline39 . Likewise with tex2html_wrap_inline41 and tex2html_wrap_inline43 .

Output

There should be N+2 lines of output. The first line of output should read INTERSECTING LINES OUTPUT. There will then be one line of output for each pair of planar lines represented by a line of input, describing how the lines intersect: none, line, or point. If the intersection is a point then your program should output the x and y coordinates of the point, correct to two decimal places. The final line of output should read ``END OF OUTPUT".
