Alright, I completely forgot about --release because i normally use just to run my stuff. That brings part 2 down to around 400ms, i am okay with that for now :D

I’d like to see your solution in total.

I set it up a bit like a game, https://pastebin.com/FGA6E7fA

My part one hovers around 600 microseconds.

Ohhh, that says my part 1 is slow already, i was sure my approach for 2 was the problem. Good to know!

I dont change the map, i just record the steps in the hashtable. But maybe drawing on the map is indeed shaving some time off, thanks for the input :)

The binary search sounds smart, would reduce the pathing quite a bit i guess :)

Part 2 i approached quite the same i think, was only a couple lines of code additionally. But running 5ms 5000 times is also gonna take a while…

I am doing the same principle brute force but it takes ~7 seconds oO

Is using a HashSet<(Pos, Dir)> for the loop detection so expensive? My CPU shouldn’t be THAT bad…

Part one around 7ms.

Also curious that i have not seen someone mention a more efficient approach, there gotta be one?

Annie are you okay?

“They” censor “our” view: BAD! “We” censor “their” view: sure, thats fine?

You know propaganda works both ways right? It’s maybe different extends, but i still believe dude is right and censorship is not the right way to go.

Somehow ensuring factual news would be amazing, but that would need to count for fucking everyonem…oh well one can dream…

I think its a thing here in norway as well. Thats why they just increase the price in early october, just a month ahead of black week bullcrap. Have seen plenty of electronics “super discounted” to the same price they had in september/october

I am just baffled by how many people pay idiotic prices with “life just got more expensive, what are you gonna do”

If people happily keep buying all the overpriced shit it’s just gonna get worse…

Why would it even be weird or anything? I only use Signal and its pretty much the same as whatsapp on the outside…just in blue. The only reason people dont use it is because “eVerYonE hAs WhAtsApP” and they dont bother. 20 useless crap apps but 2 messengers is too much
