everysingle kata u find sm1 flexing his regex knowledge lol, good job bro

True, I have no idea why I've decided to use this function

This technically shouldn't count as valid since it will consider strings containing numbers as okay.

This made me reevaluate what I know about coding. After 10 years I still have no idea.
Thank for inspiring me to be better.

same bro AHAH didn't know php can do that xD

Description does NOT specify prime divisors, but just divisors.
Anyways the statement is false:

1. return "Cuckoo Cuckoo Cuckoo Cuckoo Cuckoo Cuckoo Cuckoo Cuckoo Cuckoo Cuckoo Cuckoo Cuckoo" - you are serios? Why not same as "Cuckoo " * 12
2. Why to call time.split(":") twice?
3. Why each if-statement in one line, but the last in three?
   Too much questions.. :D

wow, this is another level. it's crazy to think the amount of "ifs" that I used and this could have been solved more simply

Mind your language please.

what the fuck are you doing..?

out laughed ahahahah
