the most efficient data structures for managing large datasets where quick access is required.
The structure of a hash table consists of:
• An array of fixed size (called buckets).
• A hash function that maps keys to indices in the array.
• A collision resolution strategy to handle cases where multiple keys map to the same
index.
9.3.1 Structure of a Hash Table
The basic structure of a hash table is an array where each index can store one or more
elements. The hash function determines the index for each key. If two keys map to the same
index, a collision occurs, and the table must handle it using techniques such as chaining or
open addressing.
