Still linear time at least, could always be much MUCH worse
There could be a hidden quadratic cost because the string needs to be reallocated and copied multiple times.
Not quadratic in the length of the input. Assuming replace is linear this is also linear
Not if I don't see it.
This is the spirit
True. Lost opportunity to blow things up with useless recursivity
The word you’re looking for is recursion (see recursion).
Thanks. I knew something was off
Nah, I'd like to un-see recursion. It was way overblown on uni, I barely ever use it.
Recursion is amazing for a small selection of problems. Most of the time you don't need, or want, it. When it is useful though, it tends to be really useful.
I don't understand people's issue with it. I always found it easy. Maybe that's why I feel this way. Maybe if you find it challenging you want to avoid it, even when it's a good solution.
