What about
a = [0,0; 2,2]; b = [1,1; 3,3];
?

Hi Celestino. I added a little bit more clarifying text to the problem statement. That's an interesting test case, but not one I will use for this problem. You could make your own extension to this problem, though!

Test case 4
a = [4 3;6 8];
b = [3 7;6 9];
The following two lines are interesting each other yet the answer is given as false.
Kindly fix it

Test Case 4 should be "true" since these lines intersect.

For Test Case 3, the two lines are on top of each other, so they will technically intersect infinite times :).

I like the conceptual clarity of this one.

For
a = [0,0; 2,2]; b = [1,1; 3,3];
a = [0,0; 2,2]; b = [2,2; 3,3];
