For day 4, I chose C. I learned C in college and it was my preferred programming language for the next decade. Obviously it has also strongly influenced many languages I've used since (C++, Java, Objective-C, etc.).

For day 3, I chose Pascal. Pascal was my introduction to structured programming and advanced data structures like linked lists and trees.

Very cool! I did the AoC 2015 Day 2 puzzle in 6502 but only ran it on a C-64 emulator (VICE). Now you're making me want to try it on an NES. 🤔

Nice! I've been having fun going back to the 2015 puzzles and doing them in different languages, roughly in the order in which I learned them. I did day 1 in BASIC. And I just finished day 2 in 6502 assembly running on a C64 emulator (VICE). Here's my emulator screenshot.

I’m doing this using languages roughly in the order I learned them. So far ive done the first three days in BASIC, 6502 assembly, and Pascal.

My solution works by slicing the maps until each range of seed IDs matches to exactly one range of location IDs. Then, I only need to check one value from each range which is a lot faster. This currently completes in about 25 ms, although there's plenty of room for improvement.
