Day 4: Printing Department
Summary
Day 4: Printing Department on Tildes centers on a grid-based puzzle from Advent of Code 2025, where fuel rolls ('@') interact with their neighbors. The thread features multiple language implementations (Elixir, Rust, Python, TypeScript, Prolog), discusses parsing the grid input, counting forkliftable cells, and a Part 2 variant that iteratively removes eligible rolls until stabilization, along with performance benchmarks and optimization notes.
