Solution: Index Pairs of a String
Explore how to implement a trie for matching substrings within a text against a list of words. This lesson helps you understand building the trie, traversing it to find valid substring indices, and analyzing time and space complexities to efficiently solve the index pairs problem.

Statement
Given a string text and an array of strings words, return a list of all index pairs [i, j] such that the substring text[i...j] is present in words.
Return the pairs [i, j] in sorted order, first by the value of i, and if two pairs have the same i, by the value of j.
