Successfully finished the second puzzle.
Took me a bit worrying what "and at most two of the Elves will be carrying any other item type" meant in the task text while my grouping loop was broken and skipping a rucksack every fourth rucksack while doing the group. Yikes.
Caught the error before trying a result though thanks to exceptions when things go wrong!
Successfully finished the second puzzle. The parsing changed so that the second column is not my answer but the intended result. I just quickly changed the file parser to replace the intended result with the fitting answer so that I need not touch the evaluation function.
Moved the previous parsing to parse_file_v1() for archiving purposes.
Successfully finished the first puzzle in which rock, paper scissor had to be evaluated into points and summed up. I wonder if there is a more elegant way of checking for wins vs losses.
