Index Pairs of a String
Explore how to efficiently find all index pairs in a string where substrings from a given list occur. This lesson guides you through using trie data structures to manage and search strings and teaches how to return sorted index pairs. By mastering this pattern, you will enhance your ability to solve substring search problems in coding interviews.
