Hello, Erlang developers! 
Ukrainian Erlanger is here! 
Today’s challenge is live, and it’s time to bring the full power of Erlang/OTP to solve it efficiently. Whether you’re leveraging pattern matching, recursion, or distributed processes, Day 18 offers a fresh opportunity to dive deeper into functional programming.
Tips for tackling Day 18:
- Parse your input methodically - structured data is easier to manipulate.
- Break the problem into smaller, reusable functions for clarity.
- If performance is a bottleneck, consider process-level parallelism for heavy computations.
Let’s collaborate and share our approaches! How are you utilizing Erlang’s unique capabilities to overcome today’s challenge? Post your solutions, optimizations, and insights below.
Happy coding, and may the beams of enlightenment guide your path!
