1. Create a Java program that prompts the user the initial choices for the Binary Search Tree
a. User chooses
1: Insert, User chooses
2: Delete, User chooses
3: Show Binary
Tree, User chooses
4: Exit Program
2. Insertion in a tree should be such that it obeys the main properties of the binary search
tree. The basic
a. If the node to be inserted is greater than the existing root, move down a level
through the right pointer of the root.
b. If the node to be inserted is lesser than the existing root, move down a level
through the left pointer of the root.
c. Repeat this process for all nodes till the leaves are reached.
d. Insert the node as the left or right pointer for the leaf (based on its value - if it is
smaller than the leaf, it should be inserted as the left pointer; if it is larger than the
leaf, it should be inserted as the right pointer)
3. Deletion is a bit more complicated than insertion because it varies depending on the node
that needs to be deleted from the tree.
a. If the node has no children (that is, it is a leaf) - it can simply be deleted from the
tree.
b. If the node has one child, simply delete the node and move the child up to replace
it.
c. If the node has two children, it becomes a little tricky. We need to find the node
which has the smallest value in the right subtree (among the elements that have a
greater value than the node to be deleted) for the node and use that to replace the
deleted node. (Note that the smallest value in the right subtree is the node that
comes immediately after the node to be deleted, implying that it is the inorder
successor for the node to be deleted).
If the user chooses to delete an element from the Binary Search Tree:
a. Display the elements in the binary tree
b. Prompt the user to enter an element to be deleted.
c. After entering a number to be deleted, show the updated elements contained in
the binary tree.

- PYTHON: Create a program that asks the user for the INORDER traversal and gives them a choice whether to pick the POSTORDER or the PREORDER, then, once they choose for either, ask their input. Let the program create a tree for the traversal from the user input. Once the program has created the tree, use the tree to identify all the inorder, postorder, and preorder traversals and print them. For instance, the user chooses POSTORDER; then, the program asks for the INORDER and POSTORDER input. The program will then identify the missing traversal - which is the PREORDER.
