    My solutions to Advents of Code in Rust

    I use itertools::Itertools which have a nice all_unique (internally, it creates a hashset and insert elements one by one unless it already contains it) but if I really wanted efficiency, I would manage my own hashset because this method is called for each character.

    my attempt at advent of code (by Isawan)

    for my solution, I used a bitset as an auxillary data structure. The trick is that since chracters are all lower case there's only 26 of them. This means if you use a u32 where each bit is a chracter, you can just OR the slice together and count the number of bits after ORing.
