Just like the first assignment, your submission on Brightspace must be a single

Just like the first assignment, your submission on Brightspace must be a single .zip file of all the Java code (including the code already given to you as part of this assignment). Do not include your entire project, which will cause the grader to accidentally import your local settings and paths. You should create the zip only from the code files, which should typically be inside your src folder.
All the code required for the completion of this assignment is already provided in the document. Additionally, a printTree method is given to you here, which you can use to verify the correctness of the structure of your tree and the values in its various nodes. This assignment is due on Brightspace by 11:59 pm, Oct 30 (Monday).
