Find Top 5 Largest Files in a Directory Tree

You are given two APIs: def list_dir(path: str) -> List[str]: """ Given a path, return the list of entries inside the directory. Return [] or raise an exception if the path is not a directory. """ pass def size_of(path: str) -> int: """ Given a file path, return its size in bytes. Raise an exception or return -1 if it's a directory. """ pass Implement the function: def get_top_5_largest_files(path: str) -> List[Tuple[int, str]]: """ Return a list of the top 5 largest files in the directory tree rooted at path. Each element is a tuple of (file_size, file_path). """ Constraints: You can assume there are no symbolic links (no cycles). Files and directories are represented as absolute paths (e.g., "/root/folder1/file.txt"). You must handle nested directories. You can assume there are no permission issues and paths are accessible.
