Solution: Index Pairs of a String
Understand how to implement a trie data structure to identify all substrings in a given text that match words from a list. Learn to insert words into the trie and search efficiently for matched index pairs, optimizing substring searching. This lesson covers algorithm design, traversal logic, and complexity analysis useful for coding interviews.

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.
