Hash Tables and Sets are powerful data structures used for fast data storage and retrieval. Both utilize hashing to map data to unique indexes, allowing for quick access. Sets, often implemented using hash tables, are collections that store unique elements with no particular order.

Key Characteristics

• Hash Table:
  • Stores key-value pairs, allowing fast lookups, insertions, and deletions by key.
  • Collisions are resolved through methods like chaining (linked lists) or open addressing (probing).
• Set:
  • Stores unique values with no specific order.
