This problem tests your understanding of recursion, Fibonacci numbers, and combinatory analysis.

In a large document processing application, analysis shows that even the largest documents use fewer than a hundred different font name/size combinations. Yet the application creates thousands of identical FontFormat objects, causing high memory usage. Which software design pattern solves this memory issue? "You used the + operator instead of concat
