Nice. From this SO answer:

https://stackoverflow.com/a/800847/415384

we get this:

https://regexper.com/#%5E(%3F%3A(%3F%3A(%3F%3A0%3F%5B13578%5...

or from another answer:

https://regexper.com/#((1%7C0(00)*01)((11%7C10(00)*01))*%7C(...)

This site is what finally made me good at regex. I found it painful to learn otherwise.

I'm 100% behind you here.

Comparing [1] and [2], there's no competition.

[1] https://regexper.com/#%5E(%3F%3A(%3F%3A(%3F%3A0%3F%5B13578%5...

[2] https://regex101.com/r/LzdGpw/1

I can use 2, but 1 just looks cool.
