How tzadiko/janestreetpuzzles works

JaneStreetPuzzles is a collection of independent programs answering monthly Jane Street puzzles, not a single application. Each solution takes puzzle-specific input or hard-coded parameters, searches, simplifies, or counts candidate configurations, and prints results. The clearest multi-layer workflow is December 2020’s constrained matrix search, supported by matrix and rule modules. Other sampled solutions are standalone puzzle solvers. The README identifies no broader product capabilities; unsampled monthly entries are therefore not assigned speculative runtime behavior.
