Great job on making it this far in the lesson on Tries! This is a very powerful data structure with many applications in software engineering, computer science, and coding interviews!
Let’s summarize everything we went over:
- A trie is a data structure that efficiently stores strings based on their prefix.
- A trie is a tree-like data structure in which each node represents a character.
- Each node’s child contains other nodes that represent subsequent characters in a string.
Triedata structure we created supported the following functions:
- Adding a word
- Searching for a word
- Counting a prefix
- Each of these functions traverses the trie starting from the root and goes through the nodes corresponding to the characters in a string (prefix or word).
- Relevant data is stored in the trie’s nodes.
- A trie can be used as the base data structure for a spell checker.
