- A list allows retrieval of information based on the contents of the information. in java True or FalseWhat are some of the similarities between string and lists?get_points("safe", "loft") // => List(A,A,C,A)get_points("safe", "gate") // => List(A,C,A,C)get_points("safe", "star") // => List(C,A,P,A)get_points("safe", "sums") // => List(C,A,A,P) Create a function called get_points which calculates the returns ,as shown above in the tests, by comparing the second word with the first word. The get_points function should output a list of 4 elements of type Letter.if a letter is present in the first word and in the correct place it should return with a "C". If the letter is present but not in the right place it should be a "P".And if the letter is not in the hidden_word then it should an "A" To do this you need to use the finder function to calculate if all the letters that are present in the first wordex. finder("safe", "loft") -> List(f) using the fix_spot function recursively analyse whether if the letter should be A,C or P. The finder function is a wrapper for the fix_spot function calling the fix_spot function with appropriate…

- java data structure Queue: Q4: A program performs the following operations on an empty queue Q: Q.enqueue(24) Q.enqueue(74) Q.enqueue(34) Q.first() Q.dequeue() Q.enqueue(12) Q.dequeue() Please show the queue contents at the end of these operations. Clearly show the front of the queue.The data structure required to evaluate a postfix expression is: A Stack. B Queue. C Tree. D Array.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…
- Write a C++ program to create a queue. The size of the queue will be dependent on the user. Insert the numbers in the queue till the queue reaches the size. Create a menu and perform the following function on that queue. Enqueue: Add an element to the end of the queue. Dequeue: Remove an element from the front of the queue. IsEmpty: Check if the queue is empty. IsFull: Check if the queue is full. Peek: Get the value of the front of the queue without removing it.Java language the top half is the class that contains the linked list parts the bottom half is the method i need help setting up should take two parameters "index" and "element" should be an actual method not just LinkedList.set(index, element); please and thank you!Data structure & alogrithum java program Create a corresponding DRIVER/Tester class that performs the following steps: 1.
