The form "dice" is plural. The singular form is "die." So you don't roll a dice, you roll a die. (Admittedly, even a lot of native English speakers don't know this!)

I "solved" this kata in its current state, but the description should clarify what is a parallel angle and what is a perpendicular angle (or at least link to a website that gives these definitions). I basically relied on my knowledge of parallel lines and perpendicular lines and hoped this knowledge would apply to angles, too.

Also: The description says that one of the angles will be specified in radians, but it's not really specified in radians, but in terms of pi. So in effect you have to convert from that to radians, then from radians to degrees.

By looking at the results of the random tests, I was able to identify specific situations in which the kata expected None to be returned, but I have no idea why!

For years, people have told me I'm not playing with a full deck. Now we finally have a way to determine whether that is true! Thanks for the kata.

Now do a beer pong kata!

Thanks! Do I need to take action on this to adopt the new framework? I'm not familiar with that process.

Oops, that comment should read "...concatenate a pound sign (hash symbol) to the result string for each of these characters."

Remember, kids: In Java, ints (including elements of int arrays) are initialized to zero. This might affect your approach to the solution.

Thanks! I was rather excited and astonished :-)

The function signature indicates that both arguments will be strings. But in the full test suite, the arguments are sometimes lists. If that's intentional, there should at least be some warning of it.

It was certainly my intention that the pile should only be burned when it is full. (This reflects the fact that in reality, I do not interrupt my raking to burn a partial pile.) I will amend the description to reflect this fact.

I don't know Lisp. Is someone else able to approve this, or do I have to do it myself?

You put a lot of work into this edit. Thank you kindly for that and the approval!

Just stopping by here to make a very sad face :((( because so far, no one has approved this and bumped it out of beta

Super fun! I wish there were a VERY VERY VERY rating!

Nice kata! I really enjoyed it, but was looking for an olympiad for 63-year-old coders :-)
