It is fun only after you understand what this Kata wants from you. I even wrote some kind of "AI" (with VERY VERY BIG quotes).
The description is horrible. It makes no sense at all. You could leave just the kata's name and info on where to get the Functions array and it wouldn't actually make any difference to the one's understanding of this kata.

The best thing you can do is to read the tests and understand what they want from you. That's how I cracked it.

Be warned that there might be some false positives when your action and kata's action both return the same result but aren't actually the same action. How do you combat this? It's up to you, this is intended.

Sorry for a bit dumb question.

Does this mean that if I do something like

float a = 1.0f / 3.0f;
float b = 1.0f / 3.0f;
System.out.println(a == b);

on one machine it's always going to be true?

Chill :c

This is beautiful

All good except my code on this one. I've gone a bit insane solving this.

Чел харош

Anyways. Any fun java katas?

It's not random stuff though. It could've been in the tests as it's a valid case.

I agree, this is not the most efficient code but it's still clever.

Could've done return x == 0 && y == 0
Welp, too late lol

Good but too much typing for a 8 kyu kata :(

Explicit is better than implicit.

A person can give you a work_pass even if it's not required and you'll have to check if it's valid and not expired.

What regex can consistently get countries from string like these:

"Citizens of Impor, Arstotzka require passport"
"Citizens of Kolechia require passport"
"Deny citizens of Arstotzka, United Federation"

I solved it without regex (check solution because spoiler)

Thanks for helping us to kill the time. Good, complex and fun.

I dedicate my soliton to the fan in my room that kept me cool during that hot process (java)

A very good and challenging 4 kya kata indeed
