Due: Monday 5/12 10:00am

Submission name: w20_traversal

For this, you will need the Tree program you can get here: https://github.com/nextcs-dw/thesource/tree/main/trees/TreeRunner

Make the following modifications to your Tree class:

  • Add three methods to the Tree class. preOrder, inOrder, and postOrder. Each should return a String which is the result of doing a pre, in, and post order traversal of a tree.
  • In your driver file, display the traversal results on the screen.
