From 5f45d9f73fa6ca0a075228048e694b84cda04a15 Mon Sep 17 00:00:00 2001 From: ddidderr Date: Sat, 25 Apr 2026 21:19:40 +0200 Subject: [PATCH] docs: add empty Sudoku example Add a fully blank 9x9 Sudoku input alongside the harder sample puzzles. This fixture gives maintainers a simple way to exercise parser handling for all-zero cells and to observe the solver's deterministic fill order when no givens are present. The example does not change solver behavior. It expands the documented example set used for manual command-line checks.
