Problem StatementYou are responsible for maintaining an employee database using an AVL tree, where each employee is identified by a unique integer employee ID. Develop a program to support the following operations:Insert a new employee into the AVL tree, considering their employee ID. Ensure that no duplicate IDs are allowed.Remove an employee with a specific employee ID from the AVL tree.Print the in-order traversal of the AVL tree after each operation to keep track of the employee database efficiently.Input format :The first line consists of an integer N, representing the number of employee IDs to insert initially.The next line consists of N space-separated integers representing the employee IDs to be inserted into the AVL tree.The last line contains an integer representing the employee IDs to be deleted from the AVL tree.

This Python program creates an AVL tree and supports operations like insertion, deletion and in-order traversal. The Node class represents a node in the AVL tree. The AVL_Tree class contains methods for performing rotations, getting the height of a node, getting the balance factor of a node, inserting a node, deleting a node and for in-order traversal of the tree.
