Solution: Longest Common Suffix Queries
Explore how to use a reversed trie data structure to efficiently find longest common suffix matches between query strings and a given container of words. Understand the process of inserting words in reverse to convert suffix matching into prefix matching, and learn how to handle tie-breaking rules for shortest length and earliest appearance. This lesson helps you implement and analyze a trie-based solution with clear time and space complexity insights.
We'll cover the following...
Statement
You are given two arrays of strings, wordsContainer and wordsQuery.
For each string wordsQuery[i], find the string in wordsContainer that shares the longest common suffix with it.
If multiple strings in
wordsContainershare the same longest suffix, choose the one with the smallest length.If two or more such strings have the same smallest length, choose the string that appears earliest in
wordsContainer.
Return an array of integers ans, where ans[i] is the index of the chosen string in wordsContainer for the query wordsQuery[i].
Constraints:
wordsContainer.length, wordsQuery.lengthwordsContainer[i].length...
