Same here tbh, my solution had some backtracking to delete redundant parts of the output so I am definitely still learning my optimizations in string manipulation.

Will PHP automatically return false or will it be null or 0? This is to make sure that the return will be what we expect - false

good idea, the second else is redundant , you can just take it off

First 4kyu in the book lets go , extracted the ranges in 5min , it's the string manipulation that took me hours to get right

interesting kata

can you recommend any reading material for it?

oh sorry :/ my bad good sense of humor though :)

we do a little trolling

I had a stroke reading the description for python :/

thanks though!
