Implement wildcard URL router
Problem Statement
Design and implement a URL routing matcher capable of handling wildcard segments (e.g., /a/*/c). The implementation must utilize a trie data structure.
Requirements
- Core Implementation: Develop the trie-based routing matcher.
- Wildcard Support: Ensure the matcher correctly handles wildcard segments like
/a/*/c, where*matches any single segment. - Complexity Analysis: Discuss the time and space complexity of adding, removing, and matching routes.
- Runtime Operations: Demonstrate how routes can be added and removed from the matcher at runtime.
- Thread Safety: Explain strategies to ensure the underlying data structure is thread-safe for concurrent access.

Core dilemma
Balancing efficient wildcard URL matching with dynamic route updates and robust thread-safe concurrent access, all while adhering to a trie-based implementation.
