- In Java, Define each of the following terms : (i) List (ii) Collection (iii) Load factor (iv)Comparator (v) Maps 2b. Discuss your understanding of Sets in Java.If F is a function and dom(F) is a set, then F is a set.Hint. Prove first that ran(F) is a setwrite in c++ Define the 3 bolded functions for the Queue (circular array): class Queue { private: double array[10000]; int front, rear, numItems; public: Queue() {front = numItems = 0; rear = -1;} bool isEmpty(); bool isFull(); void enqueue(double d); int dequeue(); void dequeueMany(int n); //remove n values from the front void enqueueMany(double values[], int n); //add n values from the array}; Hints: void dequeueMany(int n) (hint 6 lines of code, no loops, if there are more than n elements in the queue, use math to re-compute front. Otherwise, make the queue empty. Don’t forget to update numItems. void enqueueMany(int values[], int n) (hint 3 lines of code, use a for loop, call another function, but make sure there’s enough room in the array first!! )
- In Java, define the concept of a set. List additional operations that might be considered for a set.Write a struct Student that has member variables: (string) first name, (int) age and (double) fee. Write the functions as described in the class for the following purposes.1. Write a c++ function to create a dynamic sorted (in ascending order according to the age)doubly linked list, where the data component of each node is an instance of the structStudent.2. Write a function to insert the instances in the linked list. You also need to write a function to find the spot for insertion of the nodes.3. Write a function to remove the node from the linked list.4. Write a function to count the elements of the linked list.5. Write a function to determine check whether an element belongs to the linked list.6. Write a function to print the linked list (from head node) on the console.7. Write a function to print the linked list (from tail node) on the console. Implement the above functions as follows.Initially, the list must have five nodes that are the instances of the struct whose member…Design a function that consumes a natural number and produces a list ofstrings describing that many seats at a table. For example, (seats 3) shouldproduce the list (list "Seat 1" "Seat 2" "Seat 3"). Include all recipe elements. The body of your function definition MUSTUSE the build-list built-in abstract function. You may optionally use anadditional built-in abstract function. Using DrRacket
- Set and Map class templates are similar in the sense that they both use binary search trees. The difference is Set is used to store only keys while Map is used to store (key, value) pairs. Group of answer choices True False1. Create a class which implements the Set interface. 2. Create methods for intersection, difference, subset and disjoint. public interface Set{ public static final int max=10; public void add(int num); public void display(); public Set union(Set s); public Set intersection(Set s); public Set difference(Set s); public boolean subset(Set s); public boolean disjoint(Set s); public int cardinality();}for c++ A set is a collection of distinct elements of the same type. Design the class unorderedSetType. Design the class unorderedSetType, derived from the class unorderedArrayListType, to manipulate sets. Note that you need to redefine only the functions insertAt, insertEnd, and replaceAt. If the item to be inserted is already in the list, the functions insertAt and insertEnd output an appropriate message. Similarly, if the item to be replaced is already in the list, the function replaceAt outputs an appropriate message. Write a program to test your class.
- in c++ . Create a class IntegerSet for which each object can hold integers in the range 0 through 100. A set is represented internally as an array of ones and zeros. Array element a[ i ] is 1 if integer i is in the set. Array element a[ j ] is 0 if integer j is not in the set. • The default constructor initializes a set to the so-called “empty set,” i.e., a set whose array representation contains all zeros. • Provide member functions for the common set operations. For example, provide a unionOfSets member function that creates a third set that is the settheoretic union of two existing sets (i.e., an element of the third set’s array is set to 1 if that element is 1 in either or both of the existing sets, and an element of the third set’s array is set to 0 if that element is 0 in each of the existingsets). Provide an intersectionOfSets member function which creates a third set which is the set theoretic intersection of two existing sets (i.e., an element of the third set’s array is set…DisjointSet Class Implementation of this class is done in a1_partc.py A DisjointSet class represents a disjoint set which is a set of sets where every element can only belong to exactly one set. When a DisjointSet class is instantiated it is passed nothing and contains no sets. It make an empty Python dictionary which will be used to store the elements of the DisjointSet. The DisjointSet has the following member functions: def make_set(self,element) If element already exists within the Disjoint set, the function does nothing and returns false. If element does not exist in the DisjointSet, this function will add it to the DisjointSet by: make a new SetList object containing only one node, with the element as only value in the SetList adding a new dictionary entry where element is the key and a reference to the node containing element as the value return true Suppose we ran the following code: ds = DisjointSet() ds.make_set("cat") ds.make_set("dog") ds.make_set("fish")…Write the definitions of the functions to overload the assignment operator and copy constructor for the class queueType.
