Advent of Code is upon us, and I’m trying to use Swift to do it! I got the first part done. https://adventofcode.com/2023/day/1#part2 But I’m struggling with the second part. My code validates the “example” data fine, but it always tells me that for the actual data, my value is too low. While its…

[image] Paddy: cool - maybe RegEx could have helped as well. My RegEx skills suck big time, so I just used a simple string search and recorded indices for sorting purposes with my solution for the second part of day 1 using 8th programming language: { 1: "1", one: "1", 2: "2", two: "2", …

Thanks for sharing this code, I was able to piece together a magic marker reader. let fileHandle = try FileHandle( forReadingFrom: file ) if let first4Bytes = try fileHandle.read( upToCount: 4 ) { let markerID = first4Bytes.withUnsafeBytes { $0.load(as: UInt32.self) } …

Here is my 8th solution for the day 2 part 2: ns? ns: eval private var red var green var blue public : init 0 #p:red ! 0 #p:green ! 0 #p:blue ! ; : red #p:red @ n:max #p:red ! ; : green #p:green @ n:max #p:green ! ; : blue #p:blue @ n:max #p:blue ! ; : power? #p:red @ #p:gree…
