Hi,

You are correct, that error was caused by my modifications.

After some more bug solving on my algorithm we have 2 algorithms that are different and have the same outcome.

Just in one case that they are different,
my says false yours says true

members [ '56', '78' ]
rules [ [ '56', '78' ], [ '78', '56' ] ]

which brings me to the question you have brought.

You think it is better to expect that the input is clean? If we allow that it is kind of an undefined behaviour where for my algorithm result is A and yours is B. And both of them might be correct.

this is the link of the random tests => https://pastebin.com/WhBeS2a0

Hope you get it this time.

Hi there, I just did the random input testing to see how they differ.

Fixed my algorithm in a number of issues dealing with input validation.

Fixed one issue on your code dealing with repeating names in the family members list.

Still I have a matching error of .28 when comparing both algorithms.

for example

My algorithm says they can sit with this input
yours says false.
[ '64', '42', '93', '23', '75', '13', '57', '88', '97' ]
[ [ '23', '93' ], [ '64', '23' ], [ '57', '88' ] ]

You can test this on this link.

If you are going to follow up on this bug please tell me, if not, I will try to deal with it myself, so that we both have 2 good algorithms which assures that both are ok.

Thanks for helping out, I Kind of drafted the first version to see the response. You covered some error cases that I think I don't. Will fix that. And after that I will run both with random data to see if there is a difference from mine to yours, if not we have a solid solution.
