Solution: Search Suggestions System
Explore how to implement a search suggestions system by building and traversing a trie. Understand sorting, prefix matching, and how trie optimizes search complexity for product names. Gain the skills to efficiently suggest up to three products with common prefixes while considering time and space tradeoffs.
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 an array of arrays after each character of searched word is typed.
Constraints:
-
products.length -
products[i].length
