A Hashtable is a data structure that stores key-value pairs and allows fast lookups, insertions, and deletions. It is an essential tool in programming for efficiently managing and retrieving data.

Imagine a locker system where:

  • Your name is the key.
  • Your belongings are the values.
  • A locker number (computed from your name) determines where you store/retrieve items.

Instead of searching through an entire list, a Hashtable calculates an index using a hash function, allowing quick access to values.
