Leetcode 588. Design In-Memory File System
Design an in-memory hierarchical file system that supports path parsing and operations like mkdir, ls, addContentToFile (append/create), and readContentFromFile, requiring you to model directories vs files and maintain file contents. The core challenge is choosing an efficient tree/trie structure to handle traversal, creation, and listing (often lexicographically) while correctly distinguishing files from directories.
