- Problem Name: Facebook RecommendationsProblem Description: You can visualize Facebook as a graph where the nodes represent a set of users and the edges between the nodes (as a “friend” connection between you and everyone who you have befriended). Your job is to write a program that automatically computes and suggests a new friend recommendation for a user, given knowledge of the entire network. In other words, for each user, suggest the most probable user to befriend based upon the intersection of your common friends. For example, if Person A is a user on the network, Person A will get a recommendation to add Person B as their friend if Person B has the most friends in common with Person A, but B is currently not friends with Person A. The high-level idea is that for any user, you should A) go through all the other users and calculate the number of friends they have in common. B) Find the user in the social network who they are currently not friends with but have the most friends in…Create a method that accepts a pointer to a Node structure as an argument and returns a full copy of the data structure put in. There are two pointers to other Nodes in the Node data structure.Tree Define a class called TreeNode containing three data fields: element, left and right. The element is a generic type. Create constructors, setters and getters as appropriate. Define a class called BinaryTree containing two data fields: root and numberElement. Create constructors, setters and getters as appropriate. Define a method balanceCheck to check if a tree is balanced. A tree being balanced means that the balance factor is -1, 0, or 1.
