-- A solution to the advent-of-code problem, 2021, day 24: <http://adventofcode.com/2021/day/24>.
--
-- Here is a high-level summary: We are essentially modeling the ALU of a fictional
-- computer with 4 integer registers (w, x, y, z), and 6 instructions (inp, add, mul, div, mod, eql).
-- You are given a program (hilariously called "monad"), and your goal is to figure out what
-- the maximum and minimum inputs you can provide to this program such that when it runs
-- register z ends up with the value 1. Please refer to the above link for the full description.
--
-- While there are multiple ways to solve this problem in SBV, the solution here demonstrates
-- how to turn programs in this fictional language into actual Haskell/SBV programs, i.e.,
-- developing a little EDSL (embedded domain-specific language) for it. Hopefully this
-- should provide a template for other similar programs.
