Write a function that prints out Folders and Documents in order with subsequent spaces each time you go deeper into a Folder. You have two classes: Folder and Doc both containing strings to their names. In the Folder class you have two arrays defined that will contain folders and docs respectively. e.g. Folder1(root) at first level. Doc1, Doc2, Folder2, Folder 3 at second level. And Folder2 has two children Doc 3 and Doc 4. Output should be similar to Folder1 Doc 1 Doc 2 Folder 2 Doc 3 Doc 4 Folder 3
