I get out of my certification exam and there's only one thread and they put the wrong day so the admins couldn't find it.
This is why we can't have anything nice. I'll just copy yesterday's OP
Summary for those just joining us:
Advent of Code is an annual Christmas themed coding challenge that runs from December 1st until christmas. Each day the coding problems get progressively harder. We have a leaderboard and pretty good turnout, so feel free to hop in at any time and show your stuff!
Whether you have a single line monstrosity or a beautiful phone book sized stack of OOP code, you can export it in a nice little image for sharing at https://carbon.vercel.app
What did you think about today's problem?
Our Code is 2416137-393b284c (No need to share your profile, you have the option to join anonymously if you don't want us to see your github)

tripleposting my comment.... do you think you passed the exam?
First a hint: my input parser was broken because I forgot that a number could end at the end of the line
Here's my solution, the two functions left off are an ugly parser which spit out sets containing tuples (symbol, i, j) and (value, i, range[j]) and to_search(i,j) spits out adjacent squares (I did skip 0,0 but just 1-indexed instead of checking -ves, using max(x-1, 0. is kewl). If I was smarter I would've used a map/dict somehow, which would've made .contains() viable which might've been more performant, but having to search by symbol for p2 would negate that probably. On the bright side I'm learning to use iterators over loops which might help my ongoing transition to Rust programmer.

The docs have an autie explanation with steps which might help - https://doc.rust-lang.org/std/iter/trait.Iterator.html#method.fold
But I would just say that
return nums.fold(1, |n, acc| n + acc)
would be a bit like
and fold with default value is called
reduce
which sounds more like something recognisableJump in the discussion.

Yeah that's exactly what javascript reduce does
