Thanks!

Because the range stop is equal to the length of the input string rather than the length of the input string plus an underline character, and the range step is 2. Suppose you had the even-length string "abcdef" -- no matter how many characters you added to the end of it, with a range stop of 6 and step of 2, i is going to loop through 0, 2, and 4 only.

I just approved it, thanks again! I don't have any Scala experience, but it all looks reasonable to me and passes the tests, and I'm assuming you know what you're doing.

Thank you! I'm on a bus to an event right now, but will take a look tonight or in the morning depending on how late I get home.

Yes, if all three cats are in the yard, the second set of nested loops will be comparing the distances between cats 0 and 1, cats 0 and 2, and cats 1 and 2, to the minimum distance.

Thank you so much! Have you or anyone else created any solutions like that for additional languages as well?

Thanks, I just updated it with a visualization and description of one of the example tests graphs.

Gee, I was not finding any recommendations via search, I had to dig around in other katas ... I wonder if I should go after eval as well ...

Hmmm, off to find out about how to disable or detect such things, that is not something I have done before ...

I just approved it, thank you again!

Looks good, but I have one question: In randomTime, did you mean for the 50 to be 60?

Thanks, I will check it out! I had done Groovy versions of my piano katas a while back when I was playing around with Groovy a little, but didn't do them for any of my others.

Happy now. :-)

In Python, do you really want this much precision?

Testing for 0.93 and 357
It should work for random inputs too: 
14.285714285634262 should equal 
14.285714285634263
