Given the following definitions that we have used in class to represent a doubly-linked, circular List with a dummy-header node that contains data of type "struct Student". typedef struct { char *name; char *major; } Student;typedef struct node { Student *data; struct node *next; struct node *prev; } Node;typedef struct { Node *header; int size; } LinkedList;LinkedList *roster; Here is a picture of what the Linked List might look like, although you should answer the following question for a general list (ie, that does not necessarily contain 3 data items). What TYPE of data is the following: *roster Group of answer choices int int * Node Node * Student Student * char char * This is legal code, but it does not match any of the types listed above. This is illegal code, and would produce a syntax error No hand written solution and no image

Write a class that when given the MDG and the number of iterations it applies the Munch clustering algorithm and return the clustering arrangement as output. This class will contain the components from the previous questions. Appendix A contains the pseudocode of the Munch clustering algorithm using the Random Mutation Hill Climbing algorithm. However, any single population heuristic search algorithm can be used.
What would be necessary to allow the user of an OrderedStructure to provide an alternative ordering during the lifetime of a class? This method might be called sortBy and would take a Comparator as its sole parameter.
Implement a city database using ordered lists by using java. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using both: an arraybased list implementation, and a circular single linked list implementation.Use may the following node, SLL implementations to implement an ordered circular single linked list

In this exercise we will be processing some data stored as a list of dictionaries in order to be able to answer queries on the data. In our case we simply have a list of student records, where each record is a dictionary that has the student's name and their GPA. An example of the data set is below: students = [{'name': 'Alice', 'gpa': 4.0}, {'name': 'Bob', 'gpa': 3.5}, {'name': 'Cody', 'gpa': 3.75}, {'name': 'David', 'gpa': 3.65}] Your task is to create a function called topStudent which takes in a list of students of the form shown above and finds the name of the student with the highest GPA. For this assignment you can assume that no two students will have the same GPA. where you'll find a class roster of 100 students. Below that is the topStudent function, which you need to complete. roster = [{'name': 'Archy', 'gpa': 3.39}, {'name': 'Nadia', 'gpa': 2.39}, {'name': 'Cesya', 'gpa': 3.34}, {'name': 'Kellie', 'gpa': 2.32}, {'name': 'Jordana', 'gpa': 3.64}, {'name': 'Wilton',…
