1. What is the modern applications?Essential for databases, operating systems, AI, big data analytics, and network infrastructure
2. Why do computers need different data structures?Different data structures are optimized for different operations, like hash tables for quick lookups and balanced trees for sorted data.
3. How does a hash table help computers?A hash table lets computers find, add, or remove items very quickly, almost the same time no matter how many items there are.
