1. (15 pts) Defining the BSTNode structure For the first part of the assignment, you should start by designing the BSTNode class for the BST. Create a class for the BSTNode data that will have as its members a character and a string. The character will hold the English text character, and the string will hold the corresponding Morse code characters for that English text character. You should also define left and right child pointers that point to BSTNode objects. You must have a constructor that accepts arguments to set the English text character and Morse code string.
