All code implemented in this assignment should be in a class called Homework 6. You may use the data structures and algorithm code from the lecture notes. Hint: Consider using recursion. To do so implement a private helper method that takes a Node and then recursively calls itself to traverse the tree. The public method would call the private method passing the tree's root as the Node.

Create a recursive method isOrdered() that takes a Node as an argument and two keys min and max as arguments and returns true if all the keys in the tree are between min and max; min and max are indeed the smallest and largest keys in the tree, respectively; and the BST ordering property holds for all keys in the tree; false otherwise.

It will then traverse the list, verify and update the consecutive occurrences of the keyaccordingto maximum count and returns true. It returns false if no occurrence of key is found.Note: You can traverse the list only once for this task.
Create a recursive method called isOrdered() that takes a Node and the two keys min and max as arguments. It should return true if all of the tree's keys are between min and max, min and max are, in fact, its smallest and largest keys, respectively, and the BST ordering property holds for all of the tree's keys, and false if it does not.
Computer Science 1. Implement this recursive method to evaluate an arithmetic expression represented as a tree. If exp.isConstant is true, only the value instance variable is set, whereas if ! exp.isConstant, the value instance variables is not set and the others (operator, left, right) are set. private class ENode { // invariants: boolean isConstant; // true for leaf nodes, false for operator nodes int value; // only has a value if isConstant char operator; // if ! isConstant, can only be '+' or '*' ENode left; // null if isConstant, not null otherwise ENode right; // null if isConstant, not null otherwise}public static int evaluate(ENode exp) { // YOUR CODE HERE}
