Search Suggestions System
Explore how to implement a search suggestions system using a Trie data structure to efficiently suggest up to three products matching each typed prefix. Understand handling prefixes, lexicographical ordering, and constraints while coding in C++. This lesson prepares you to solve string search challenges commonly asked in coding interviews.
We'll cover the following...
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
