Project #53791 - Binary Search Tree - Java

BST

Requirements: implement methods for the following BST operations: search, insert, tree-traversal (pre, in, and post orders), count (leaves, internal nodes), height.

Approach: you may start from the BST in our textbook (Figure 7.25: Listing of the Implementation of a Binary Search Tree Structure in Sorting Data Structures and Algorithms Using Java by William McAllister) for any available methods, and implement only the new ones. Generate a BST by repeatedly inserting at least 20 keys (starting from an empty tree). Then, perform the following operations in the prescribed order showing the results after each of the following operations (or implement a menu with choices. It doesn’t have to be a GUI. Displaying the menu and the results in the output window of the IDE is fine):

    • in-order traversal;
    • search for an existing key;
    • search for a key that does not belong to the BST;
    • calculate the height;
    • count the leaves;
    • count the internal nodes;
    • insert a new key;
    • calculate the height;
    • inorder traversal;
    • preorder traversal;
    • postorder traversal;
    • count the leaves;
    • count the internal nodes;

Deliverables: You should submit (1) all the source (.java) files, (2) an output sample (screenshot with program execution showing the required functionality) and (3) a document file describing your solution. The solution description document should include the following elements: a short problem analysis, main design decisions, assumptions, description of classes, user interface, testing and test cases, error handling and lessons learned. The size of the document should be of 3 pages, single spaced, font size 12. All solution description elements should be properly formatted using APA style.

                                                   

Wrapp all the files in a single .zip archive and name it Project3_your_name.zip
