42 is only the correct answer for the example test...

Thank you!

I thank you very much!

That explanation is definitely clearer.

As a massive English nerd, I would probably go a step further, phrasing it:

Find the greatest difference in length for any possible pairing of strings between Array1 and Array2.

or

Find the greatest diffence in length when comparing strings in Array1 to strings in Array2.

Also, thank you g964 for your many wonderful kata contributions.

• You can read the instructions in the following manner:
  For every string x in the first array and for every string y in the second array calculate abs(length(x) − length(y)) and then take the max of these numbers.
  Is that clearer?
• The full tests of every kata are always hidden, it's the rule. Sorry for that!
• No need to post uppercase letters; it is considered as a bit rude:-)

Yeah the instructions are AWFUL. Can't they elaborate the instructions ? And why can't we view the full tests ? There's only one test case where as "submitting" runs extra test case which aren't available to us. If we could view them, I can actually decipher what needs to be done, to excuse the poorly written instructions...
