I also got stuck on the incorrect wording. I think correct would be simply: "If arr does not contain 5 and 13, function should return: "It's a white array""

I see no fixed test for PHP with input value of 0 and this doesn't seem to generate a 0 either: $n = rand(1, 1e6) are you sure about it?

Same problem with PHP

Fixed.

Which language?

I believe this is still should be worded better.

Saying "If arr contains neither 5 nor 13" implies you're looking for the case where there is no 5, as well as no 13 (both have to not exist). What the white array is really testing for is a case where there is either no 5 or no 13 (only one of those does not exist).

Perhaps you could say "If arr either does not contain 5, or it does not contain 13, we should return "It's a white array".

Changed. Cheers O_o

Hi @myjinxin - that still seemed ambiguous to me...

Better to say If arr contains neither 5 nor 13, we should return "It's a white array"

done.

ok, I'v fixed it.
Thank you ~~

dear robjar,

Please explain your problem in detail, thank you!

I don't understand, why it is incorrect? can you explain?

You're right indeed. It reminds me that getMonth and getMonth() is definitely not the same thing. I made this test an example test case as well. Thanks.

Sorry about that, the right format is definitely 'mm/dd/yyyy'. Thx
