java language create a class named as MyDeque having function add to head and add last function using linked list and make a separate class and make object of your class

for c++ please List ReverseModify the linked list class you created in the previous programming challenges byadding a member function named reverse that rearranges the nodes in the list so thattheir order is reversed. Demonstrate the function in a simple driver program. here is my first programming #include <iostream> using namespace std; struct node { int data; node *next; }; class list { private: node *head,*tail; public: list() { head = NULL; tail = NULL; } ~list() { } void append() { int value; cout<<"Enter the value to append: "; cin>>value; node *temp=new node; node *s; temp->data = value; temp->next = NULL; s = head; if(head==NULL) head=temp; else { while (s->next != NULL) s = s->next; s->next = temp; } } void insert() { int value,pos,i,count=0; cout<<"Enter the value to be inserted: "; cin>>value; node *temp=new node; node *s, *ptr; temp->data = value; temp->next = NULL; cout<<"Enter the postion at which node to be...

struct insert_at_back_of_sll { // Function takes a constant Book as a parameter, inserts that book at the // back of a singly linked list, and returns nothing. void operator()(const Book& book) { /// TO-DO (3) /// // Write the lines of code to insert "book" at the back of "my_sll". Since // the SLL has no size() function and no tail pointer, you must walk the // list looking for the last node. // // HINT: Do not attempt to insert after "my_sll.end()". // ///// END-T0-DO (3) ||||// } std::forward_list& my_sll; };

Array_based circular queue: Define the class Queue using one dimensional circular array representation with no implementation; i.e. declare the data members, and the function members only (Enqueue, Dequeue, IsEmpty, GetHead etc.). Implement the Ennqueue method of the above class

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")...
