benchmarking is the only way to find that out.

I think a solution for maximum performance would look quite different and would be significantlyfaster (10x to 20x faster i would totally guess). Usually regular expressions are only faster if your programming language is not so performance (like early perl/php implementations I guess).

This was a million years ago, but I'm wondering about the performance of this solution. It's certainnly very readable and elegant once you know a little about regex. Are there multiple iterations involved? How does that work under the dashboard?

wow

Hmm, regex is always cool, much like an epigraph 🤔.bt clean.

What's funny is that the better solution is the one nobody talks about

This is the best solution. Nice.

never thought of using regEx like this. its actually pretty cool !

Floored by this! A proper use of RegEx, in my view.

Amazing!

Amazing!!

Note that this has time complexity O(N^2) while it's possible to achieve O(N).

Never mind, the piece of optimisation I failed to figure out was checking for a set rather than the entire string. My bad.

I continuously timed out with this exact solution...

I'm new to programming and if I'm wrong please someone correct me!

I believe it's because it's being considered to be null terminated strings.
Therefore the last character of these strings are '\0', but in a empty string this would be the only character
and when we compare it with a string that isn't empty it would return true since '\0' is present in both.

But as far as I understand it isn't something that will be printed in the screen, just something that will be
considered by the machine.

I would never believed that multiple line js would be faster than than one line js regex. Can you tell me if in general using regex is slow?
