There is a problem wtih the test case: "The array was: [-1,1,0,-1,1,0,-1,1,0,0]: expected +0 to equal 2". Because the first index meeting the requirements is 0 but it expects to return the second satisfying index.

Fixed. Remember mentioning the language.

There seems to be a bad test case.
It failed on the array of: { 7, 3, 3 }
It expects an answer of 0, but there is no answer, so it is -1.
However, in the 'printed' test case, it shows { 7, 3, -3 }, which DOES give an answer of 0, so I think there may be a typo in the test case, where one of the threes is missing a negative sign.

NVM I read wrong: The test is telling my code is failing because for {8,8} should give me -1 and it's giving me 1 (which is totally wrong)...

Sorry ^^;

Hi there, I am having doubts about Length 2 sized arrays.
When n=0, there is nothing at the left (because there is no -1 position), so the answer should be 1 if position 1 equals to 0.
When n=1, there is something at the left (position 0) and nothing to the right (last position), so the answer should be 0 if position 0 equals to 0.

So I don't understand why {8,8} should be 1! I mean, n is not being counted, but the numbers at the left and at the right of n, isn't it?
Am I misreading something or missing something?

Java:

• method name should be camelCase, not PascalCase

Refer here on how to enable backward compatability to not invalidate all solutions

Reraised as an issue :-)

great job !!

@Awesome A.D.: thanks for the tip about printing during the test phase...it's a good thing to know (which I did not). Big thumb's up!

python, maybe others: there should be a fixed test for 0

• done
• done for all languages

done

Awesome, works like a charm now, thanks!

Ruby:

• Tests need update to Ruby 3,
• The block with fixed tests seems to be not correct because it emits no assertions.
