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

what the fuck are you doing..?

what a hack! i didn't knew that you can use expressions in switch-case. Cool, but is it good practice?

Is '12-34:56-78:90-12' a correct MAC-Address? Your solution says, it is.

Cool, as i written my code i didn't knew how i can ged rid of a while-cycle. Your recursion-Solution is much elegant for this case. I have forked your solution and written it shorter, with just one return and better readable condition :)

Thank you, i finally understanded it and made my solution better ;P

bad practice, if you change the input variables.. $dm reproduce, how many damage you'll get from one monster, but if you change it, it will reproduce another value: sum of damage you'll get.
It works. but bad coding style

P.S. c==11?2 is a hack, because i don't understand what the test want from me.

?11=??
111=11
2=11=22
311=33
411=44

i can put there any number 1-9 and it will be correct! but the test fails if i didn't return exactly 2?

And this should be a good code?

just use single return.. your expression already return true or false, why return true, if expression returns true and false if not? ;) NOTE: IN php is 1 equals to true, 0 is equals to false :-P

No, because he have a cycle, that take 6 from $nb_petals while nb_petals > 6 :D

wtf are you doing
