Q When writing BST algorithms, you need to be able to print the tree in a hierarchical order to verify that the algorithms are processing the data correctly. Write functions to create a BST and then to print the tree. The printed output should contain the node level number and its data. Present the tree using a bill-of-materials format, as shown below for the following hierarchy of Input Output devices. F 1. Input Output Devices 2. Fax Machine 3. Barcode Reader 3. Headphone 2. Keyboard 3. Joystick 3. Optical pen 4. Plotter 5. Scanner 6. Webcam
