Traversal BST assignments

Question

I was writing a method to print a BST in traversal order. Also, to represent the depth of each node, I wish to place a tab or "/t" string within the word to represent depth. The problem is that when I run the code, I get the result:

It does not print out the last element and times does not have the same indent as worst. I was thinking that maybe my mistake is that I am not allowing the else loop to be accessed as much as I need it to be I expected something like this to print out

Answer 1

To print a tab, you use "\\t" (note, that is a backslash). "\\t" is called an "escape sequence" .
