advent-2021-kotlin VS Advent_of_Code_in_Pascal

Once I finally understood how the examples worked with subpackets, I was able to come up with what I think is a nice clean solution. I ended up using an Iterator that got passed around to various sealed types that would parse themselves out. I defined several extension functions on Iterator to make things easier to read.

Free Pascal - 2251/1744 34.5 seconds runtime No objects, no recursion After brute forcing part 1, I stared at part 2 until I though only handling the different values of X,Y,Z and letting the grid represent variable size cubes.. only to hit memory size limits anyway... and then I learned how to use BITPACKED array, and was able to eventually brute force part 2. Whew!
