Here’s my take on day7. I implemented the first part as a special case of part two (using just one worker). This makes part 1 less optimal, but the running time is still good enough.
The curiosity of my approach is that I made a stream which emits all intermediate states. Part 1 then boils down to taking the last state and fetching the processed items. Part 2 amounts to counting all the states and decrementing it by one.
