🤯Nicely made - but I am lost somewhere!
Well - in short, my code "works" for the visible tests and not for the random ones - of course 😝
Given a matrix as:

 1 -1  1  1
 0  0  0 -1
 0  0  0 -1
 1 -1 -1  0

If I understood the rules correctly, the 1 placed third in first row represents that the person indexed 0 and the person indexed 2 know each other in a friendly manner. Because index 0 is always LOL, index 3 should also be LOL.

However - the result is Dota...

Where am I wrong??

Honestly, I cant get everything right at the first go; well of course. Thanks a lot for the link, I am very sorry that I missed it somewhere before.
Well, I published this challenge because I just unlocked the ability to do so - I am happy to receive help so fast 🙏

When I was writing the challenge, it asked me to upload my solution along. So.... Should I just copy that to the "Test Cases" and perform a random test against my solution?

Oh that! It's more of a typo than an issue in my algorithm. Dont worry, you are not supposed to use any mind reading magic.
Thanks for pointing that out - and poof - it's fixed.

By the way, it does seem like you read my mind and figured out what I expected in turn - kudos!

Probably the worst solution ever, because of method local inner classes 😝.

I wrote some good amount of mess to solve it... As far as I understand my own code (which I forgot right after writing) the algorithm seems to be working just fine! Well the results are of cource not correct 😝. Here are a few tests

tft,^& = 2
ttftff, |&^&& = 36
ttftfftft,|&^&&||^ = 23296
tt, | = 1
ttt, || = 2
tttt, ||| = 6
ttttt, |||| = 24

If anyone has a clue, please help me out 😁.
