#been doing some definitly unsafe shit for advent of code#didnt want to do propper bounds checking today so my solution relies on the fact that the data is 140x140 and my matrix is 150x150#yesterday was a little odd aswell cause i was doing like pattern matching without regex#don't think my solution was super unsafe or anything but pointer arithmetic is not something ive done in the past really#tried re-writing it w/ regex (in C) but i discovered the hell that is different regex versions#spent way too long figuring out how regex.h (POSIX regex lib) worked only to discover that POSIX regex is like... not very good...#like posix regex doesnt even have non-capturing groups???#(and regex101.com doesnt support POSIX ere/bre)#ended up writing a pretry swanky solution w/ regex in python and someone in my school's AOC discord put it in a oneliner lol
