Design Linux Command 'cd'

meta Design a simple Linux 'cd' command to simulate Unix directory navigation. Implement the function change_directory(current_path: str, path: str) -> str. Parameters: current_path is the current directory location. path is the user input path which could be '../', '', or a subdirectory name. Return the resulting directory path after executing 'cd'. Assumptions: The path always begins at the root directory '/'. If it's an absolute path, it starts with '/'; otherwise, treat it as relative. Use '/' to separate hierarchical directory levels. Examples: change_directory('/', 'home') returns '/home' change_directory('/home', '../') returns '/' change_directory('/home', 'user/files') returns '/home/user/files' Example Input / home
