Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

SPOILER FLAG! DAMN YOU!!

22 in the test Series is correct.
Base Series 1,2,4,8.16,22
Test Series 15,20 (first iteration) ,22 (2nd iteration)
Number of iterations in the Test Series to Converge => 2
You only count the number of iterations you need in the Test Series to get to a number in the Base Series.
No, the "original number" here is 20 (yes, this a really bad choice of words).
Right, so the 'original number' in this case would be 2, not 20?
Multiply all the non-zero digits and add the result to the original number
I'm confused about one of the samples tests. Given a seed of 15, the number of numbers added to the test sequence before converging with the base is
apparently 2 numbers...
Base Series: 1, 2, 4, 8, 16 .....
Test Series: 15, 20, 4(?!), 8, 16 ...
It's my understanding that the number in the test series after 20 should be 22.
=> 20 => [remove 0] => [no other digits to multiply 2 by] => [2 + 20 = 22]
Do I have this wrong?
