Yep, this is terribly worded. If special characters and numbers need to be matched, why even bring them up?

I'm still having this issue for js.

description reads:

!Spaces will be ignored but special characters and numbers won't match the string and return false.

When my code encountered a character that does not match /[a-z]/i and is not a space, it would return false. The random tests generate @ symbols and numbers and expect then to be treated no different from letters.

Duplicate of plenty knapsack problems.

Description does not mention that a solution is always possible ( total price of products will always exceed 500 yen ). No performance testing ( 4 kyu? really ?!? ). Description could make more clear that card can only be used when purchases cost more than 500 yen, not more than or equal to. Description's English is a bit broken.

The description is still very bad: the actual behaviour is "space will be ignored but special characters and numbers won't". So you have to match them as well.

As GiacomoSorbi said: Suggestion and not an issue.

I could do that if the author is ok with it, but it would make the kata a tad more complicated for strings with length <2.

And I would consider it a suggestion, not an issue that prevents the kata from being approved :D

This rule checked both basic test and random test, look at basic test 3 and 2

"each of the two letters are not continuous", maybe this should be checked in test cases.

yes, it is alike but at least you can view the source code at first to determine the char set...
this site works terriblly on phone browser anyway.

Maybe it is the same problem when you try to decode a Web page with hidden chars?

I do not think there could be a good description on this kata except all the test cases shown or all possible chars declared.
Such code can run out with correct result only under certain condition, which means you should know all the conditions. Thanks to the console.log we can know hwat line comes and then hwat to fix, or we could only get mad.

Maybe it is the only trap of this kata! :D

HAHA, My computer can not display handwriting font...
