## In this assignment, we are going to implement a few methods for BSTMapping ## 1. Initializer: make sure we can use a list to do initilization ## 2. height: height of binary search tree ## 3. preorder: pre-order traversal of the binary search tree ## In this assignment, we are going to implement a few methods for BSTMapping ## 1.
