If the kata wants a different purpose, it needs the tests to support it.

These are intentionally simple, so developers new to ruby can learn. In fact, I've been using these to teach 10-14 year olds the ins and outs of the Enumerable module, because it opens up so much they can do in Ruby. They have a very low kyu rating to reflect that.

it helps if you print the input inside your function.
puts text
the text = "'" is tricky.

Same here. Test 7 is failing and I can't figure out why.

I guess ties are inputs making several differen results possible. For example, "aa bb cc dd". Such cases are not tested, so there is no need to care about them.

Yeah, I talked about it a little in my other comment. It's probably the part of the kata I'm most unsure about, I know it's unneeded, but I thought it would help people to learn what they needed for graph searches if they hadn't done anything like it before. I dunno, what do you think?

Typically we're waiting for 10 upvotes with associated beta feedback. Just saw it hit 10, so it's on the list to get finalized any. minute. now...

Once any kata has enough upvotes and rank feedback (don't know the exact number for either), one of the admin's will push it out of beta

Same deal here. Can't figure out what test 7 is, and have written lots of edge case tests to try to figure it out.

Test 7 is the one I can't figure out -- hint, anyone?

me too :/ also i probably don't understand what "ties" are, i searched on google but had no good matches.
Maybe they are the "-" in a composite word like "three-quarters"?

also struggling with test 7!!

Could you prompt what is the problem in 7th test.

Good point. Fixed.
