Write a function that reverses a linked list, with this argument: pointer to pointer to the head node.

Delete a given value from a BST rooted at given node. Returns a pointer to node.

Get the successor of a value in a BST rooted by given node. Returns int.

Write a method is_binary_search_tree that returns true if a given tree is a BST (use helper function).

Using an iterative approach, write a function find_node(bst_node* root, int target) that returns the node with the given target value in a BST.
