AdventOfCode VS Advent_of_Code_in_Pascal

Solution First solved this in Excel. Here'a snapshot of the mess. After doing it once, writing code to do it for any input turned out to be surprisingly much easier than I had hoped for.

Solution read as a fixed width file, so that all digits became a separate column. After that it was simple column operations.

I did it last year, was a great learning experience and tons of fun seeing everyone else's solutions. Am doing it again this year too. I plan on posting solutions to the thread and Github

Solution

I'm doing it in Lazarus/Free Pascal again.

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!

My pascal based solver eventually got valid text out of your input.
