Consider the decision model/game theoretic model from Chapter 19 for the spread of a new behavior through a social network. Suppose we have the social network depicted in Figure 2; suppose that each node starts with the behavior B, and each node has a threshold of q = 2/5 for switching to behavior A. Now, let c and d form a two-node set S of initial adopters of behavior A. If other nodes follow the threshold rule for choosing behaviors, which nodes will eventually switch to A? Give a brief (1-2 sentence) explanation for your answer. Find a cluster of density greater than 1 − q = 3/5 in the part of the graph outside S that blocks behavior A from spreading to all nodes, starting from S, at threshold q. Give a brief (1-2 sentence) explanation for your answer. Suppose you were allowed to add a single edge to the given network, connecting one of nodes c or d to any one node that it is not currently connected to. Could you do this in such a way that now behavior A, starting from S and spreading with a threshold of 2/5, would reach all nodes? Give a brief explanation for your answer.

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:
To remove from a linked list all of the nodes that have the same key, you need to devise a plan.

Nim is a two-player game The rules are as follows. The game starts with a single stack of 7 tokens. At each move a player selects one stack and divides it into two non-empty, non-equal stacks. A player who is unable to move loses the game. Draw the complete search tree for nim. The answer is as given:
Define a class called Player that implements Comparable <Player> with health and name attributes and has getter/setter methods to retrieve/access them. Define the appropriate constructors and give it a useful toString() method. Define a class called LinkedList with an inner nested class Node. The Node class has private attributes(Player player; Node next;). Define the appropriate constructor and toString() methods. Class LinkedList has two attributes (Node head and int size). Define the following LinkedList methods: insert(Player p); remove(Player p); toString(); NOTE: your insert() method must be ordered. This means that your newly added Node should be placed in an ordered fashion such that you resulting linked list is ALWAYS sorted by the players’s health. For example: If Player p has health 2000, then insert() will produce the following linked list: p -> null If Player p2 has health 1000, then insert() will produce the following linked list: p2->p->null If…
