Description isn't clear. The given link had a better explanation of expected output. More examples would be useful.

Maybe the problem was changed, but this wasn't a problem for me.

I guess the docs don't explicitly mention that all? short-circuits too. The same is true of none? and any?, by the way.

Temporary objects will be created in memory anyways. I prefer to avoid line wrapping and indent-nesting when possible.

Also updated valid9 criteron because there was no guarantee of only positive numbers.

You're right. His solution doesn't correctly validate all sudokus - it just passes all the test cases. Find any valid sudoku and swap the 6th and 7th rows to create an example invalid solution that this solution incorrectly passes.

It is unclear when and where code is called/run due to the (presumably intentional) obfuscation.

Finding the solution to this kata felt unrewarding to me.

The provided hints were mostly unuseful, and this kata ended up just being a ton of trial and error attempts to get a direct reference to the ADMIN object.

I've a couple test cases that demonstrates how this problem is insufficiently defined and needs more test cases:

voters1 = [ [:a, :b, :c], [:a, :b, :c], [:a, :b, :c], [:b, :c, :a], [:b, :c, :a], [:c, :b, :a], [:d, :b, :a], ]
voters2 = [ [:a, :b, :c], [:a, :b, :c], [:a, :b, :c], [:b, :c, :a], [:b, :c, :a], [:c, :b, :a], [:d, :b, :a], [:e, :b, :a], ]

For example, @hencethus and @evilscott/@Dima83 have differing solutions that pass the tests. However:

@hencethus's solution maintains tallies across iterations, disqualifying losers along the way.

• voters1 - no winners because :a and :b tie during the second iteration
• voters2 - declares :b as winner during the second iteration

@evilscott's and @Dima83's solution declares the candidate with the most first-votes to be the winner rather than the one with "more than half the total votes"

• voters1 - finds the winner to be :a during the first iteration
• voters2 - finds the winner to be :a during the first iteration
