> Was there something in particular you were looking for and didn't find? Mostly dealing with allocation - ie dynamic string handling, reading strings from a file, passing a string to a function, and returning a different string to another function and so on. Ed: this was pretty much before solving concrete aoc problems, just figuring out how to read "suffix" from standard input, passing it to a function "prefix_suffix", getting a string "prefix suffix" back and outputting that string; trivial manipulations, but lots of dynamic allocation.
