I wish I was as smart as these people.
I'm inclined to say that some people 'just get' certain things like this or complex SQL. How they got to 'getting it', I don't know.

Re: Regex that only matches itself
#12I think I might be missing something. Wouldn't something like "a" be a valid 1-byte regular expression that only matches instances of "a"?

Your regex is actually /a/ which does not match the string "/a/".

I would say that adding slashes is quite arbitrary constraint, and it is really language specific syntax that is limited to minority of languages (I believe it was introduced in Perl). If you do regexp in Java, Python, C you don't use slashes.
Edit: looks like slashes weren't even used in the example.

Everybody is a Genius. But if you judge a fish by
its ability to climb a tree, it will live its whole
life believing that it is stupid.

It's a pretty boring question if you don't make that requirement, though. The whole exercise is arbitrary, so it doesn't bother me.

Probably not Einstein http://quoteinvestigator.com/2013/04/06/fish-climb/ (not that it matters in any deep way).
