Solution: Search Suggestions System
Explore how to design a search suggestions system that provides up to three products sharing a common prefix for each character typed. Understand both naive and optimized trie-based approaches to improve time complexity while handling prefix matching effectively.
Statement
Given an array of strings called products and a word to search, design a system that, when each character of the searched word is typed, suggests at most three product names from products. Suggested products should share a common prefix with the searched word. If more than three products exist with a common prefix, return the three product names that appear first in lexicographical order.
Return the suggested products, which will be a list of lists after each character of searched word is typed.
Constraints:
-
products.length -
products[i].length
