Question

Design and implement serialization and deserialization for a trie that stores a large dictionary of words. Requirements: compact wire format; explicit end-of-word markers; resilience to malformed or partial input; streaming-friendly encoding; and forward/backward compatibility for future fields. Provide pseudocode for both serialize and deserialize, analyze complexity, and discuss handling of Unicode, optional compression, and memory limits.
