ah, thanks for clarifying. I was sure that's how I read it but I've been calculating the difference between the first and last element ([2,34,2] incorrectly yields 0) in a 3 amigo array (which can work with the array sorted).

Hi,

From the example in the description, shouldn't the first 3 Amigos be [2, 34, 2], range 0 and even parity.

Here's what is shown as the result at the moment:

ex1
Input = [1, 2, 34, 2, 1, 5, 3, 5, 7, 234, 2, 1]
Result = [5,3,5]

this was a comment on the solution, so didn't think it would be accessible to those that haven't solved the kata yet. anyway, I shall mark any comment with code as spoiler, thanks for the reminder! :)

This was the missing piece 'all methods in ruby that accept a block will also accept a block parameter as the last argument'. Thanks!

sure, I can add a bit more clarity to description as suggested.

Makes sense! I have fixed that now. Also, thanks for that detailed explanation, very helpful

hi,

thanks for pointing that out, but how is changing the input possible like this, and how can I fix that ..

I hadn't changed anything, and tried it again just now with positive result. Odd, have to find out what's going on. I am open to any insight.

Test.assertDeepEquals(badApples([ [ 1, 0 ], [ 0, 5 ], [ 0, 7 ] ]), [ [ 1, 5] ]);

You have passed all of the tests! :)

I ran the test and it passed. could you run the test on its own under sample tests?

here are the two tests that were reported as fails:

Test.assertDeepEquals(badApples([ [ 5, 5 ],[ 0, 6 ],[ 6, 0 ],[ 4, 2 ],[ 2, 7 ],[ 2, 4 ],[ 6, 7 ],[ 5, 6 ],[ 4, 2 ] ]), [ [ 5, 5 ],[ 6, 6 ],[ 4, 2 ],[ 2, 7 ],[ 2, 4 ],[ 6, 7 ],[ 5, 6 ],[ 4, 2 ] ])
Test.assertDeepEquals(badApples([ [ 1, 0 ], [ 0, 5 ], [ 0, 7 ] ]), [ [ 1, 5] ]);

Time: 343ms Passed: 2 Failed: 0
Test Results:
Test Passed: Value deep equals [[5, 5], [6, 6], [4, 2], [2, 7], [2, 4], [6, 7], [5, 6], [4, 2]]
Test Passed: Value deep equals [[1, 5]]

hmm, odd, I ran the test and it passed. could you run the test on its own under sample tests?

thanks for spotting that, checking now.

hey thanks for spotting that, checking now.

Hi,

Sure,the output for [ [ 1, 0 ], [ 0, 5 ], [ 0, 7 ] ] should be [ [ 1, 5] ], and you are correct in your explanation. We sort out bad packages from the top of the fruit box, so [ 1, 0 ] and [ 0, 5 ]gets dealt with first. [0,7] remains and will have to be discarded (as per condition) since the package can't be populated with a spare.

Cool, thanks for the link.
