look into types ;)

Thanks, edge case :) No it work

Hmm..
I have write a Java solution and submit it.
It seems no error in the tests.
Made some changes in the random tests:

1. Added "Testing for candies = [...]" 
2. Added "Expected: [...], instead got: [...]" when testcase failed.

Some possible problem in your code(just guess):

1:
When candies = [single integer]
your code should return [0,n], instead of [1,n]
2:
don't modify the input array.

Can you paste your code here and mark it as having spoiler content?

Ah, sorry. I haven't seen your reply :(
It seems that you are using JAVA?
I copied this testcase to the fix test, it returns {78,20}
I think the JAVA translation mey contains errors, but I don't know JAVA.
Let me try, or waiting for @theropodMusings to check it.
Thanks for your feedback ;-)

Hi, any clue why isn't working?

Thanks -- I'm glad you enjoyed it and that you figured out the problem!

Case close.
It was my fault. Edge case :)
Very good Kata :)

On one hand there have been 91 successful Java completions so far, so I assume the random tests are OK, but on the other hand bugs can always turn up. Do you want to try posting your solution as a reply, and then marking it as a spoiler, and I can take a look at it? (I haven't asked anyone to do that before, but I would think that as the kata author I should be able to see comments marked as spoilers.)

Java

Hi! What language are you using?

Sample test works OK.
"2, 15, 8, 14, 7, 2, 3, 11, 7, 19, 6, 16, 15, 19, 19, 5, 5, 17, 4, 5, 5, 12, 13, 1, 17, 4, 5, 11, 3, 4, 5, 11, 5, 3, 13, 15, 11, 19, 17, 16, 5, 4, 6, 5, 12, 17, 15, 3, 17, 6, 4, 7, 10, 5, 8, 5, 9, 2, 17, 13, 13, 19, 1, 14, 18, 15, 4, 4, 1, 14, 9, 1, 8, 16, 17, 13, 13, 16, 9, 12, 13, 2, 10, 14, 16, 15, 18, 17, 2, 16, 16, 9, 14, 3, 8, 12"
it's one of test. It return "expected:<[[0], 12]> but was:<[[1], 12]>"
In my local environment response is "78, 20"

Removed(from initial code, not preload).

Are you sure that your result is right?
Please give me the input data, thanks ;-)
