Solving the task on typescript, I had the same problem, but I solved it.
The problem concerns the test that follows the test that you are looking at, with the data
a1 = [3,4];
a2 = [0.25];

revise your solution algorithm, and deal with the output of debug information

Got pleasure doing this kata! Thanks and follow

Yes. Thank you!

Thank's for you kata!

But. Why for the test data [[1, 2], [4, 5], [3, 4], [6, 9], [7, 10]] in the tests for the typescript, the answer is (30.60) (48, 60) (45.60) (40.60) (42.60)?
60/9 will not be an integer.
My code gives the answer (90,180) (144,180) (135,180) (120,180) (126,180)
and passes all other tests, including random.

Thank's. Nice kata!
