I was writing a method to print a BST in traversal order. 我正在编写一种以遍历顺序打印BST的方法。 Also, to represent the depth of each node, I wish to place a tab or "/t" string within the word to represent depth. 另外，为了表示每个节点的深度，我希望在单词内放置一个制表符或“ / t”字符串以表示深度。 The problem is that when I run the code, I get the result: 问题是，当我运行代码时，会得到结果：

It does not print out the last element and times does not have the same indent as worst. 它不会打印出最后一个元素，并且时间没有最差的缩进。 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 我当时在想，也许是我的错误是我不允许我尽可能多地访问else循环，因为我期望这样的打印出来

To print a tab, you use "\\t" (note, that is a backslash). 要打印选项卡，请使用"\\t" （注意，这是一个反斜杠）。 "\\t" is called an "escape sequence" . "\\t"被称为“转义序列” 。
