A tip: you could just replace list with sorted to make it shorter
sort = lambda x: ''.join(sorted(filter(str.isalpha, x)) + sorted(filter(str.isdigit, x)))

And it's also sorting less element

My bad, gonna fix it now. Thanks!

Edit: Done! And added 2 more test case (0 and 100 USD)

Any whitespace at the end of the line should also be stripped out.

Any form of whitespace should only be removed if it is trailing behind the sentence

This solution teaches me how to use a made function (Not the lambda one) on an Arrays stream's map

Had to implement all those function from scratch as I hate and suck at Java lmao. My previous code submission was from the golf one (Not allowed apparently).

Straight away
Edit: Done!

No, it's not. That's Javascript's function you are referring to.

Edit: And as I've said before this kata haven't yet translated to Python

Were you not in the python section of the training page?
https://www.codewars.com/kata/582a53ed261c2af9d200018c/train/python

Edit: There haven't been a Python translation on this kata

You know i guess it's mostly because of the title Regex validate PIN code

should be abcdefghijklmnopqrstuvwxyz: 'abcdefghijklmnopqrstuvwxyz' should equal 'abcdefghijklmnopqrstuvwxy'

The assertion in Test Case is flipped

Thanks to whom approved it and ejini for telling me! (Man, the approval notification didn't work)

And I think this is a spoiler comment. Flag your code as spoiler next time ;)

Java Updated Fork

• Added 100 random test cases

Yep since the constraints are in range of 1-20 anyway.
Edit: Is it bad? And should I change it?

Please don't post your solution on Discourse page as other warriors can see your solution. This is not a question. If you want to see others' solution you can go to this section or simply head to a Solution button in between the Details and Forks button.
