- 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…What would be the content of the list from left to right of the following code //each node contains a string and a pointer to the next Nodeclass Node{ public String name; public Node next; public Node(String name) { this.name = name; } public Node() { name = null; }}//********************************************//A list of Nodesclass Students{ Node front; public Students() { front = new Node(); }// add nodes to the list public void add(String s ) { Node cur = front; while(cur.next!= null) { cur = cur.next; } Node n = new Node(s); cur.next = n; n.next= new Node(s); } }class Driver{ public static void main(String[] args) { Students list = new Students(); list.add("a"); list.add("b"); list.add("c");list.add("d"); list.add("e"); list.add("f"); }}What would be the content of the list from left to right order. class Node{ public String name; public Node next; public Node(String name) { this.name = name; } public Node() { name = null; }}//********************************************//A list of Nodesclass Students{ Node front; public Students() { front = new Node(); }// add nodes to the list public void add(String s ) { Node cur = front; while(cur.next!= null) { cur = cur.next; } Node n = new Node(s); cur.next = n; n.next= new Node(s); } }class Driver{ public static void main(String[] args) { Students list = new Students(); list.add("a"); list.add("b"); list.add("c");list.add("d"); list.add("e"); list.add("f"); }}
