Contact dictionary can be implemented using hash table for fast lookups with O(1) time complexity.
Use a hash table to store contacts with keys as names and values as contact information.
Example: { 'John Doe': '555-1234', 'Jane Smith': '555-5678' }
Time complexity for searching, inserting, and deleting contacts is O(1) with a hash table.
