Trie vs Hash Table
Understand the key differences between Tries and Hash Tables, including their handling of common prefixes, lookup efficiency, collision resolution, and memory use. Learn which data structure is optimal for dictionaries with long or shared prefixes in Java.
Comparison between Trie & HashTable
One might wonder what is the need of using Tries
when we can implement dictionaries with Hash Tables as well. A simple answer to this would be, yes, you can use Hash Tables to build dictionaries, but if you need a fast lookup and have long words which share common prefixes then a Trie is the perfect data structure for you. It also makes storing words easier, as the implementation is very simple. Some of the key points which differentiate a Hash Table from Tries are given below:
1. Common Prefixes
