/* PROMPT:
Help me parse this terminal output using C#. The output represents a series of `cd` and `ls` commands, these commands start with '$'. if a `cd` command is followed by `..` this means to move up a level. otherwise it means to navigate to the folder whose name is given.

The remaining output is either a file, which is shown by file size and followed by file name, or it is a directory which starts with `dir` and is followed by the directory name. 

Here is an example input: */
