Adapted #adventOfCode 2025 day 1 in #LuaLang to use less memory to fit on #ti92 Plus. Execution time: 2m 42s.

The TI-92+ has a 12 MHz 68000 and 188 KB RAM that is also used as the calculator's main ramdisk, meaning, the Lua interpreter, script, puzzle input, and all datastructures must fit in that size. The calculator runs on 4 AA batteries with a battery life of "well beyond a school year".
