Solution: Longest Common Suffix Queries

Explore how to solve longest common suffix queries by constructing a reversed trie with words from the container. Understand the insertion process to store optimal candidates and the querying process to find suffix matches efficiently, along with analysis of time and space complexities.

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 wordsContainer share 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:

  • 1≤1 \leq wordsContainer.length, wordsQuery.length ...
