Yes, thank you!

Huh, GREAT kata! Not too happy with my own solution, but, at least - it exists! :)

79228162514264337593543950340 should be the power of two. Few wrong tests, after all this time.

That doesn't make any difference. I just wanted to say that the rank is a relative thing. :) Btw, my rank here is higher than i deserve. Also, some 7kyu or 6kyu katas can be harder than 5kyu katas, for someone. Peace.

print(lcs('abcdefghijklmnopq', 'apcdefghijklmnobq')) #This test has broken my "solution" too.

Same here, too. Strange. But, is it actually, correct? Sum of divisors for 441 is 300, if i am right?

Ok, thanks, now I tried, and i failed on this example/test: [15, 13, 7, 26, 10], 30). Output should be 3, right? (15+13),(10+7),(26) Or, i guess order is important. Ok, got it.

Could I ask: how many vehicles can pass in the same time? How many tracks are on the road? Are two vehicles in one pass - max?

35 characters min, here too... Walrus didn't helped too much... :)

I know. That's why i said that more tests are needed? If 99,9% tests are passed with the false "solutions", people will have tendency to hard code problematic part. :)

Hm, re-check your solution again. Universal solution can handle datasets like this....

I have a feeling that my solution will time out, for sure, but, let's try. :) Seems very challenging.

Pretty nice, and easy (at least in Python). I have seen several 5 kyu katas which are much, very much harder...
