youre close to your given runtime but using arr1.sort() and arr2.sort() at the start ruins it - try arr1.reverse() and arr2.reverse() instead

I've noticed that other letters are -5 from original ones, but wanted to emphasize that tests aren't strong enough to check it :(

You should consider to add this check!

well, I don't even see MY OWN solution in C completions for some glitchy reason. the numbers show that it exists, but the page ALSO says there "are no codes to show". also strange: you've gotten ahold of an OLDER version of my code, missing the n parameter. so, keep in mind that you were "tweaking" code that probably wouldn't work anyway with the final code structure.

No. Your solution is not O(len(arr1) + len(arr2)).

Approved, thanks for your contribution!

JavaScript translation awaiting approval.

yes, the examples given in the description are different from the sample tests. I have checked them, rigorously. You shouldn't use the ISSUE tag unless you know there's a problem with the kata code and can describe it or give some evidence. Anyway, if you remain stuck, you can post your code (with a spoiler tag), and I can take a look for you. cheers

You're very welcome. I remember getting stuck on that for a while.

wow I missed that "different". thanks, RM

Those words have two os in them, so go against this part of the kata description:

a valid response word must contain four different letters

Something seems off with the Python version. If neither Alice nor Bob have a valid word for the input string, then -1 should be returned. But if there was at least one match during the game, then either 0 or 1 should be returned, correct? I get the following result with one of the random tests:

input string: logy
input number: 1
Bob: logo
Alice: loco
Bob: lobo
Alice: no word found

Test expected: 1 should equal -1

As far as I understood, your current DISPLAYED sample tests in Python are not the same as REAL sample tests, but testing outputs coincide (or I did smth wrong...).
All in all, I passed all the tests several times, but couldn't pass two of sample tests below. I think you should check it!

Wow this guy is really smart

• 00 can be a palindrome only if it's not a string, and if it's part of a bigger number (e.g. 100)
• 0d0 should not be one, as it's clearly a string (there is a letter in it), so it's not numerical
