Heap Sort

A Heap is a type of data structure that is built on trees. It's a binary tree that's virtually complete. Except for the very bottom level, all levels of the tree must be filled in a heap. The last (bottom) level should be filled from left to right. The heap data structure is used for the efficient implementation of priority queues.Heap can be of two types:

Draw how an item can be added to the front of a doubly linked list. (show the steps in multiple pictures)
def remove_after_kth(items, k=1): Given a list of items, some of which may be duplicated, create and return a new list that is otherwise the same as items, but only up to k occurrences of each element are kept, and all occurrences of that element after those first k are discarded. Hint: loop through the items, maintaining a dictionary that remembers how many times you have already seen each element. Update this count as you go, and append each element to the resultlist only if its count is still at most equal to k. items k expected results [42, 42, 42, 42, 42, 42, 42] 3 [42, 42, 42] ['tom', 42, 'bob', 'bob', 99, 'bob', 'tom', 'tom', 99] 2 ['tom', 42, 'bob', 'bob', 99, 'tom', 99] [1, 2, 3, 4, 5, 4, 3, 2, 1, 2, 3, 4, 5, 4, 3, 2, 1] 1 [1, 2, 3, 4, 5] [1, 2, 3, 4, 5, 4, 3, 2, 1, 2, 3, 4, 5, 4, 3, 2, 1, 2, 3, 4, 5] 3 [1, 2, 3, 4, 5, 4, 3, 2, 1, 2, 3, 4, 5, 1, 5] [42, 42, 42, 99, 99, 17] 0 [ ] Please add comments between the codes so I can understand
How do I prevent "quit" from being reversed and appended to the new list?
We need a linked list to hold information about penguins in a zoo. You will need the following integers for your IntNode (see below). I have included sample values for one of the penguins: penguin ID: 45821 penguin weight (kg): 11 penguin height (cm): 90 We now need to track the number of penguins in the zoo. I would like to propose a better way to track the size of the list. Rather than traversing the list every time you need to know its size, why not keep a variable called listSize that increments every time you add a node to the list and decrements anytime you remove an item from the list? public class penguinList { //nested class IntNode goes here private IntNode first; private int listSize; //...the methods of penguinList class go here } Now, you just need to increment the listSize instance variable in every method that adds a node to the list. If you have any methods that removes a node from the list, decrement the listSize instance variable in those methods instead.…
You should create a method and call it findTotalleaves (); this method will find all of the nodes that are considered to be leaves, which are nodes that do not have any BNode dependents. The public function must not take any arguments, but the private method must accept as a parameter a BNode that represents the current root.
Hello thank you for the solution. Is there also a way to format the list without using the .join method, and just using f' strings, perhaps in a list comprehension?
Change the insert and _insert methods accordingly to comply with the new format. - If a new word is inserted that has a matching sorted order of its letters as an existing Node, do not insert a new Node. Instead, modify the existing Node and append the inserted word into the list.
