У меня у одного решение не отправляется?

you need to return a value, not print

ohh yeah that worked, thanks!

Try changing the version to PHP 8.0 in the kata trainer

Parse error: syntax error, unexpected '<', expecting end of file in /home/codewarrior/run.php on line 19

Anyone know how to handle this? Its appear only when trying to attempt solution :/

Its happen on PHP, even if havent a single code char in solution.

Nice Kata, it combines 2 simpler ones. If you've come across those, then this one is a lot easier.

I see now! Thanks for that! I didn't realize for a second that it meant alphabetical characters have no distinction between capitalized and non-capitalized.

Your solution fails another test, you read the logs wrong. It returns wrong answer for "abcdeaB".

Indivisibilities
defaultdict(<class 'int'>, {'I': 1, 'n': 1, 'd': 1, 'i': 6, 'v': 1, 's': 2, 'b': 1, 'l': 1, 't': 1, 'e': 1})
Repeated characters = 2

Why is this wrong? I am returning the correct number of repeated characters but it is still marked incorrect.

first i thought this kata is so tough, i tried every data structure which is possible to solve it like stack , vector.
i always lazy to solve it.
but, when i solve it then i realize this is only 15 lines of code with correct logic.

It is great, but has O(n*m) time complexity. The optimal solution to this problem is -> O(n)
