Write a function ConnectedComponent (G,v) which takes as in- put a dictionary representing a graph G, and one of its vertices v, and returns a set of nodes representing the connected com- ponent of v, implementing the method given in the notes. Hint: Create and update lists called visitednodes repres- enting previously visited nodes, latestnodes representing the most recently visited nodes, and newnodes representing nodes neighbouring those in latestnodes and not included in either of the previous categories.

- A1 Write a function Connected Component (G,v) which takes as in- put a dictionary representing a graph G, and one of its vertices v, and returns a set of nodes representing the connected com- ponent of v, implementing the method given in the notes. Hint: Create and update lists called visitednodes repres- enting previously visited nodes, latestnodes representing the most recently visited nodes, and newnodes representing nodes neighbouring those in latestnodes and not included in either of the previous categories. A2 Write a function NumberOfComponents (G) which takes as in- put a dictionary representing a graph G and returns a positive integer representing its number of connected components. A3 Recall that an ordinary (unweighted) graph can be considered a weighted graph by assigning every edge weight 1. The "shortest path" from a to b in this interpretation is simply the path from a to b with the fewest edges. This makes Dijkstra's algorithm simpler as the shortest path from a to b…Implement a program using Doubly LinkedList. Your doubly linked list should store information of students (Reg_no., Name, CGPA, city, age). Your program should provide following functionalities: Insert at Front Insert at Rear Insert in middle Delete from front Delete from rear Delete from middle Display all the data Data Structures in C++ Needed urgent i will thumb up for youLinked list. Complete the function that takes as a parameter the head of a linked list and prints the linked list in reverse order. If the linked list had the contents: of,the,and,on,a,an,ok. Then the correct output would be: ok,an,a,on,and,the,of. Given: struct node { char word[31]; struct node *prev, next; }; void print_reverse(struct node *head) { }
- Implement a function void printAll(void) to print all the items of the list.Add a new public member function to the LinkedList class named reverse() which reverses the items in the list. You must take advantage of the doubly-linked list structure to do this efficiently as discussed in the videos/pdfs, i.e. swap each node’s prev/next pointers, and finally swap headPtr/tailPtr. Demonstrate your function works by creating a sample list of a few entries in main(), printing out the contents of the list, reversing the list, and then printing out the contents of the list again to show that the list has been reversed. Note: your function must actually reverse the items in the doubly-linked list, not just print them out in reverse order! Note: we won't use the copy constructor in this assignment, and as such you aren't required to update the copy constructor to work with a doubly-linked list. This is what I have so far but its not working! template<class ItemType>void LinkedList<ItemType>::reverse(){ Node<ItemType>*curPtr,*prev,*next;…Complete the examples in the docstring and then write the body of thefollowing function:def same_first_last(L):""" (list) -> boolPrecondition: len(L) >= 2Return True if and only if first item of the list is the same as thelast.>>> same_first_last([3, 4, 2, 8, 3])True>>> same_first_last(['apple', 'banana', 'pear'])>>> same_first_last([4.0, 4.5])"""
- Merge2AscListsRecur that combines the nodes in X-list and Y-list into Z-list such that, after calling the function, Z-list is a sorted list (in non-decreasing order) containing all the nodes initially contained in X-list and Y-list – X-list and Y-list should both be empty after the call. The function should: ► Have only three parameters (each a pointer-to-Node) and no return value (be a void function). ► Not use any global variables or static local variables. ► Not use any looping constructs (for, while, do-while, ...). ► Be directly (not indirectly) recursive. ► Not create any new nodes, destroy any existing nodes or copy/replace the data item of any node. ► Not make temporary copies of the data involved using any other storage structures (arrays, stacks, queues, etc.). ► Use (if ever needed) no more than a small number of pointers to hold certain link addresses. ○ Not make temporary copies of the…Write a function that takes a list removal(L), delete from it all the elements whose indicesare divisible by 3. And return the resulting list after removing unwanted elements.Example:>>>removal(['A', 'B', 'C', 'D', 'E'])['B', 'C','E'Write a function, to be included in an unsorted linked list class, called getLargest, that will return the largest item in the list.
- 5. The following function indexCounter aims to find and return all the indices of the element x in a list L. if x is not in the list L, return an empty list. However, the implementation has a flaw, so that many times it will return error message. Can you fix the flaw? def indexCounter(L, x): indexList [] startIndex = 0 while startIndex < len(L): indexList.append (L.index (x, startIndex)) startIndex = L.index (x, startIndex) + 1 return indexListwrite a C++ Program Your task is to develop a program for a hospital where they need help to calculate and maintainthe number of patients, their disease, and their allotted room numbers. You will use a SinglyLinkedList to store record of a patient such as patient name, patient CNIC, patient disease, admitdate and patient allotted room number.Suppose if a patient has been recovered then, you will need to delete his Node from the list (Useall methods of deletion Start, Middle, and End). The system will use a special function named asDichargePatient() that will take patient CNIC as parameter, remove node of the patient, and returnsuccess status of the operation.Whenever a new patient is arrived at the hospital for admitting in a room. The system will useanother function AdmitPatient() that takes patient’s information, checks the availability of a room(assume that hospital only have 20 rooms and only one patient per room is allowed). If multiplerooms are available, then always allocate…For this assignment, you need to implement link-based List and derivative ADTs in Java. To complete this, you will need the following: A LinkNode structure or class which will have two attributes - a data attribute and a pointer attribute to the next node. The data attribute of the LinkNode should be the Money class of Lab 1. A Singly Linked List class which will be composed of three attributes - a count attribute, a LinkedNode pointer/reference attribute pointing to the start of the list and a LinkedNode pointer/reference attribute pointing to the end of the list. Since this is a class, make sure all these attributes are private. The attribute names for the Node and Linked List are the words in bold in #1 and #2. For the Linked List, implement the most common linked-list behaviors as explained in class - getters/setters/constructors/destructors for the attributes of the class, (a) create new list, (b) add data, (c) delete data, (d) find data, (e) count of data items in the…
