Oh, I see, I for some reason switched zip operation with โ€œcreate pair/tupleโ€ operation in my head. Thanks for clarification.

Wouldn't this code fail in a case like this? Because you count different lines, not different characters in the lines, right? Or am I missing something? Thanks (Let's ignore column symmetry for the sake of example).

(I think you will get answer 100, but the answer is 300)

But for sure after seeing this I have to learn Scala.

Was lazy at the beginning, so I started to do actual expansion in memory, then decided to do it properly. And it paid off in the second part.

  • find galaxy coordinates + hold few bit masks to find unused rows and columns โ†’ convert to indexes
  • transform original galaxies coordinates considering number of previous empty lines (time for simple binary search)
  • use the Manhattan distance

Double expansion seams like a nice approach, but I didn't think of that. Instead, I just scan the lines and โ€œrememberโ€ if I am in a component or not by counting the number of pipe crossings.

That's looking quite promising. The main thing missing before being ready for me is filter/add by region and of course shop name. Then it can go out i think (+ give me a random code feature as the next step).

And make a new post with this, no one will notice otherwise (if you haven't already)

This is the same thing as in chrome

Reading this on Infinity for lemmy

 

Hi, I was wondering if there is an app that enables loyalty cards sharing. When you open it, you can enter your card code of the Store. Now you can use a card of any other participant who entered his own card for the Store (the backend will send a random one) and your code can be used by anyone else using the service. Usually the cards are just permanent ID (shown as a bar code), so it shouldn't be that hard to implement.

While using this, the shop would have no chance of creating a profile on you and tracking you (as the purchases would be โ€œrandomโ€), they have these data anyway. You would only give up the data you fill in when you ask for the card.

Do you know something like this? Or am I missing something important, or do you see some major flaws in this design (I don't use loyalty cards, but sometimes they could be quite useful)? Thanks
