   TypeScript Easy puzzle to cross the half the mark, while it took me sometime to figure out how to solve it without creating a large two dimensional array, I wonder how much time it takes for Eric Wastl to create so perfect precise puzzle inputs, thank you again.

    Raku 3695/5712 because 23 of the 34 minutes I spent on part two were spent tilting my head trying to interpret the strange letter forms instead of switching the order of my for loops so the letters looked like they were printed on a single portrait-orientation letter page rather than on a dot matrix printer with accordion paper. Probably another three minutes were spent trying to understand what the heck "Eight capital letters" meant and why there was no stated part 2 output for the part 1 input.
