Solution: Index Pairs of a String
Explore how to implement a Trie to solve the problem of finding all index pairs [i, j] in a text where substrings match words from a list. Understand insertion and search operations in a Trie, optimize substring searches, and learn to handle time and space complexity for efficient string matching.

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.
