Write a method void listAllFiles(File dir) that recursively displays a list of a directory's files and subdirectories. An example is illustrated below.

Note the following in the output:

Directory names are all capitalized and written between brackets [ ].

Files and subdirectories are indented in order to illustrate to which parent directory they belong.

Use a helper method void listAllFiles(File dir, String spaces) where dir represents the root directory (i.e., Folder 1 in the example below) and spaces stores a number of spaces " " that is incremented every time the method is recursively called.

The helper method should print out spaces followed by the file or subdirectory names.
