Trie: When Arrays and HashMaps Fall Short
Tries are often overlooked, but they're incredible for prefix-based operations and autocomplete features.
Some real-world uses:
- IP routing tables
- Autocomplete suggestions
- Spell checkers
Here's what clicked for me:
When you're dealing with strings and need to check prefixes frequently, tries can turn O(n*m) operations into O(m). It's like having a tree-shaped dictionary where each path spells out a word!
Let's discuss:
- What's your favorite trie application?
- How do you handle trie memory optimization?
- Share a problem where trie outperformed other data structures
What's your approach to trie node design?
