Project Euler #912: Where are the Odds?

I have spent a little time with Project Euler. Is it very popular with those here at HN?

I don't know that I'd gauge anything by popularity with the HN crowd. It's also a diverse group. I'm closing in on a hundred problems solved, in a not very completion-ist fashion (I've got a whole bunch of skips and random choices of puzzles).

Maths isn't my strongest suit, and I have no academic comp-sci background, so there's been a number of these I sort of brute force and then go read the answers in the thread; or I brute force the first few integers in the sequence and then try and wrap my head around what https://oeis.org/ is attempting to tell me about them.

It has challenged me a bit on some of my fundamentals with programming, really making me think about efficiency etc.

While I've done most of the problems in rust so far, I've been having to refresh my knowledge of Go recently, so I've started porting answers between the two languages, and it's definitely helping there a bunch.
