Search Suggestions System

Explore how to implement a search suggestions system with trie structures. Understand how to efficiently generate at most three lexicographically smallest product suggestions based on the typed prefix in a dynamic search input.

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:

  • 11 \leq products.length 1000\leq
