O(n^2) ... not the best approach

worst practice

The cast (int) is unnecessary because - '0' already gives the int value

Very cool! Congrats for such a nice solution :)

holy shit - why?

take a look at 15:15 🕦 are you sure? 😂

Took me some minutes to understand whats going on here :D smart trick

In this case a well designed class would have a field position which would be an ENUM e.g. Position.BOSS, Position.WORKER ... :)

This one is cool

Your solution is buggy! For example 4fff1aaaaaaaaaaa your code returns true because fff is length 3 -> --count = 1 -> 1*10 +1 = 11 = aaaaaaaaaaa.length()

Java automatically converts arithmetic operations on bytes into an integer value. So your cast (int) is unnecessary. Additionally, you should not change the method signature to satisfy this kata.

This is an anoying kata

this is b€€€s€€€

Cool - i didn't know this method. kudos
