Trie

Trie is a tree like data structure that is used to store strings efficiently, especially when prefix based operations are required. It is also known as Prefix-Tree.

Specification of the Data Structure:

• Words are stored character by character.
• Common prefix are shared.
• Each path represents a prefix.
• Some of them are marked as words.

What is the purpose of using a Trie data structure?

Determine the number of words that begin with ‘ca’.

[car, cat, cap, cup, cupboard, cut, cutter, cot]

Advantage’s of Trie Data Structure

• Prefix-based operations: It efficiently supports prefix searches, making it ideal for autocomplete and search suggestion systems.
• Efficient searching: Trie allows fast search, insertion, and deletion operations in O(L) time, where L is the length of the word.
