JAVA please Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts Code provided in the assignment ItemNode.java:

To finish up the definition of the Node class, we need at least two constructor methods. We definitely want a default constructor that creates an emptyNode, with both the Element and Link members set to null. We also need aparameterized constructor that assigns data to the Element member and setsthe Link member to null.Write the code for the Node class:

PYTHON: Please help me modify this program. Instead of putting the letters/nodes in the code, please change it to accept user input of inorder and preorder traversal rather than putting the nodes in the code itself. I also inserted an image below because I am trying to print out the same output as the image. I you can modify it just like the image, then please do.

A skip listThe second programming homework is already on a server (http://marmoset.famnit.upr.si).In this task, a skip list data structure should be implemented. You can follow the followinginstructions:- Implement the class NodeSkipList with two components, namely key node and arrayof successors. You can also add a constructor, but you do not need to add anymethod.- In the class SkipList implement a constructor SkipList(long maxNodes). The parameter maxNodes determines the maximal number of nodes that can be added to askip list. Using this parameter we can determine the maximal height of a node, thatis, the maximal length of the array of successors. As the maximal height of a nodeit is usually taken the logarithm of the parameter. Further, it is useful to constructboth sentinels of maximal height.- In the class SkipList it is useful to write a method which simulates coin flip andreturns the number of all tosses until the first head comes up. This number representsthe height of a node…
