Edit: Nevermind, I missed the part where I return the first string if equal and shifted my array.... works now (DERP)

Added the suggested tests to 10 (more or less) of the available languages, I'll finish adding them some other time.

That's not php, I mean Spiro's code.

Your code is wrong, it's counting a as 0,b as 1, etc.

Each letter of a word scores points according to its position in the alphabet: a = 1, b = 2, c = 3 etc.

Yeah, I noticed the random tests had some errors. I manually added up the expected and it wasnt higher than my actual....

My bad

No very helpful.... I submitted a few times and it passed finally... Don't see my mistake and 'Yes' isnt very condusive.

Yes.

Your goal in this kata is to implement a difference function

I mean...

Expected: Array (
)
Actual  : Array (
    0 => ''
)

If the string is empty, the result should be empty array too.
