Hello, Erlang adventurers! 
Ukrainian Erlanger is here 
once again to tackle today’s challenge, Day 19, where we roll up our sleeves to arrange towels with precision and elegance. 
This is a fun puzzle that combines string matching and creative pattern decomposition, making it perfect for Erlang’s recursive power and functional approach.
Tips for Tackling Day 19
- Parse the Input Efficiently: Split the towel patterns and desired designs into manageable data structures (e.g., lists of strings) for easy processing.
- Pattern Matching: Use recursion to match the towel patterns against the desired designs. Erlang’s pattern-matching capabilities make this a natural fit!
- Memoization for Speed: To optimize the solution, consider caching intermediate results, especially when checking if a design can be created from the available towels.
- Iterative Refinement: Start with simple designs, verify your approach, and gradually handle more complex cases.
Erlang Power in Action
Functional elegance is our strength. Let’s fold these towels into the perfect solution! 
This puzzle feels like a satisfying exercise in creative recursion and problem-solving. Share your approaches, insights, and challenges here - whether you’re a veteran Erlanger or exploring for the first time, we’re here to BEAM together!
Happy coding and may your towels always align perfectly!
