Intersection of two lines#5134
Find the intersection point of two lines. Each line is defined by a pair of distinct points lying on it.
Each of the next two lines contains four integers, the coordinates of two distinct points on a line. The integers in each line are x_1\ y_1\ x_2\ y_2, |x_i| \leq 100, |y_i| \leq 100.
Print 0 if the lines do not intersect. Print 1 if the lines intersect at exactly one point, and print 2 if the lines coincide.
If the lines intersect at exactly one point, print in the second line the coordinates of the intersection point with digits after the decimal point.
