(Code in Java)
Using the binary search tree (BST) data structure, we can sort a sequence of n elements by first calling an
insertion procedure for n times to maintain a BST, and then performing an Inorder-Tree-Walk on the
BST to output the elements in sorted order.
The improved insertion procedure will make
• 2 comparisons to insert a node with key = 1
• 3 comparisons to insert a node with key = 3
• 2 comparisons to insert a node with key = 8
Program Requirements
In this programming assignment, you will implement in Java this sorting
the improved insertion procedure. Note that each node of a BST is an object containing four attributes:
key (for the value of an element), lef t (for its left child), right (for its right child), and p (for its parent).
Please add a static counter to track the number of key comparisons made by your algorithm. Your program
will output the following
1. The size of the input array,
2. The input array,
3. The list of array elements after sorting, and
4. The number of key comparisons made.

Using the binary search tree (BST) data structure, we can sort a sequence of n elements by first calling an
insertion procedure for n times to maintain a BST, and then performing an INORDER-TREE-WALK on the
BST to output the elements in sorted order.
To insert a node, we've discussed the TREE-INSERT procedure in class (also from page 294 of the text-
book). This TREE-INSERT procedure can actually be improved to reduce the number of key comparisons
so that each node's key is compared with the new node's key for at most once during each insertion. For
example, given the following BST,
6.
The improved insertion procedure will make
2 comparisons to insert a node with key = 1
8.
3 comparisons to insert a node with key = 3
2 comparisons to insert a node with key = 8
Program Requirements
In this programming assignment, you will implement in Java this sorting algorithm using BST, by using
the improved insertion procedure. Note that each node of a BST is an object containing four attributes:
key (for the value of an element), left (for its left child), right (for its right child), and p (for its parent).
Please add a static counter to track the number of key comparisons made by your algorithm. Your program
will output the following
1. The size of the input array,
2. The input array,
3. The list of array elements after sorting, and
4. The number of key comparisons made.

Python’s built-in list and dictionary types have copy methods that perform shallow copies. Using the following dictionary dictionary = {'Sophia': [97, 88]} demonstrate that a dictionary’s copy method indeed performs a shallow copy. To do so, call copy to make the shallow copy, modify the list stored in the original dictionary, then display both dictionaries to see that they have the same contents. Next, use the copy module’s deepcopy function to create a deep copy of the dictionary. Modify the list stored in the original dictionary, then display both dictionaries to prove that each has its own data. Please use python and keep it simplearrow_forward

The program should have a 'populate' button that obtains a string from the user, creates a sorted binary search tree of characters, and prints the tree using the DisplayTree class. It should also print the characters on one line in sorted order by traversing the tree in inorder fashion. The program should also have a 'Trim Tree' button that obtains a second line of input to delete characters from the tree, trimming the tree accordingly. It should ignore characters that are not in the tree, and only delete one character for each occurrence in the second line of input. When all characters from the second line have been deleted from the tree, the program should print the remaining characters in the tree using the DisplayTree class. The output should be labeled appropriately, and no spaces or commas should be used between tree elements in the inorder traversal.Here is the…arrow_forward
