My solutions to Eric Wastl's Advent of Code 2024 in C, C++, and Python.
Below I timed the runtime of my solutions on my input files. All timing done on Apple M4 Pro.
Differences in timing between languages depend on my level of familiariy with the language, the efficiency of that language itself, and the different method or algorithm I happened to choose when solving that puzzle in that language, and how long I actually spend trying to make it fast. Also, sometimes the language I use first will be faster because the second time I implement a solution I understand the problem better.
