Solution: Index Pairs of a String
Explore how to use trie data structures to efficiently find all index pairs of substrings in a given text that match any word from a provided list. Understand building a trie and traversing it to identify substring matches, optimizing search time and managing space complexity effectively.

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.
