Thanks for flagging, no idea how that happened. Fixed.

Slight edit might be required from the Instruction page:

This line:

If there aren't enough spare chairs available, return

Should be updated to:

If there aren't enough spare chairs available, return 'Not enough!'

i.e. missing the 'Not enough!'

Thanks, and thanks for flagging the issue - fixed across the whole series (I hope!) :D

Great Kata series!
Not sure if it's just me, the hyperlinks to the other challenges in the series doesn't seem to work. e.g.

The Office I - Outed
The Office II - Boredeom Score
The Office III - Broken Photocopier
The Office IV - Find a Meeting Room
The Office V - Find a Chair

More than happy to fix this myself (if it is indeed an actual bug and not just me) - not sure how to do the edit though. Any tips?

When I changed the test case to like this the code fails?

var arr = [10, 12, 10, 8, 12, 7, 6, 4, 10, 12];
Test.assertSimilar( highestRank(arr), 12);
