illustrate the execution of the in-place heap sort algorithm in the following input sequence: {2, 5, 16, 4, 10, 23, 39, 18, 28, 15}. note: please write down each step clearly and draw the visual effect of the node tree.

Develop Java methods to perform the following operations on an unordered list (using linked lists). What is the complexity of each of these algorithms. 1. Insert an element at the start (front) of the list 2. Insert an element at the end (rear) of the list 3. Insert an element at the middle of the list  following an element already in the list. 4. Remove an element from the middle of the list

Sorting  Create a MyLinkedList class with inner Node class, data fields, and the insert(element) method.  Implement a toString method to return all nodes in MyLinkedList.  Implement a recursive sorting and a non-recursive sorting method.
