I'm rather new to the site as well, so I can relate and you're absolutly right about the limits in general.

If you click on your kyu you can see Discourse->Conversations to find your comments again and there is an Edit button next to your comment.

Have fun on this site

The generator function is not already defined as the description mentions.

Unfortuantly I saw that right after I submitted the feedback, I am rather new to the site and I have no clue how to edit the post (heck, I didn't know how to see my comment until after I got a notification about your reply). Either way I think the question would be better if the team size was not fixed, in general I find it best not to make solutions only work for arbitrary limits.

I don't know if he has changed it but it clearly states at this point in time that there are "Two teams of 5 members"

The acceptance test cases always have the same number of players, there should be some variety there as the problem does not explicitly state team size.

People should be punished for making assumptions about the size of the team and that he team 2 anchor will be index 4 of the second array.
