B1 Write a function NearestPoint (G,v,mylist) which takes asinput a networkx object G representing a weighted graph, anobject v which will be a node of G, and a list mylist of someother nodes of G. The function should return whichever nodein mylist is nearest to v (in the sense of the minimum weightpath from v). In the event of a tie, it should return the nearestnode which appears earliest in mylist.CORDELIA WEBB UNIVERSITY OF LEEDS, 2023/24B2 We say that a weighted graph has the Unique Weight Prop-erty (UWP) if no two edges have the same weight. Recall fromWorkshop 9-10 that if G is connected and has the UWP then itwill automatically have a unique spanning tree. Write a func-tion UWP (G) which tests whether or not G has the UWP andreturns True or False accordingly.Hint: extract a list of edge-weights and use the count func-tion to see how many times each appears.B3 Write a function GoodPath (G,a,b) which takes as input a net-workx object G representing a connected weighted graph withUWP and objects a, b which will be nodes of G. Your functionshould return True if the shortest path from a to b lies entirelyinside the unique minimal connector and False otherwise.

A linked list is said to contain a cycle if any node is visited more than once while traversing the list. Given a pointer to the head of a linked list, determine if it contains a cycle. If it does, return 1. Otherwise, return 0. Example: head refers to the list of nodes 1 → 2 → 3 → 1 → NULL. There is a cycle where node 3 points back to node 1, so return 1. Function Description: Complete the has cycle function provided in the moodle assignment folder. It has the following parameter: • SinglyLinkedListNode pointer head: a reference to the head of the list. Returns: • int: 1 if there is a cycle or 0 if there is not. Note: if the list is empty, head will be null. Input Format: The code stub reads from stdin and passes the appropriate argument to your function. The custom test cases format will not be described for this question due to its complexity. Expand the section for the main function and review the code if you would like to figure out how to create a custom case. Constraints:…
Given a singly linked list, print reverse of it using a recursive function printLinkedList( node *first ) where first is the pointer pointing to the first data node. For example, if the given linked list is 1->2->3->4, then output should be: 4 3 2 1 (note the whitespace in between each data value)
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;…
In this problem you will implement a function called triangle_countwhich will take as input a graph object G, representing an undirectedgraph G, and will return the number of triangles in G. Do not use anyimports for this problem. To simplify the problem you may assume thateach edge is stored twice in G. That is if an edge goes from u to v then vwill be in u’s collection and u will be in v’s collection. If you would prefer,you may assume that an edge is only stored once. In either case G willneed to be regarded as undirected.
Write a function that gets a linked list of ints, and reverses it. For example - on input 1 -> 2 -> 3 -> 4, after the function finishes the execution, the list becomes 4 -> 3 -> 2 -> 1 - If the list has one element, then it doesn’t change - If the list is empty, then it doesn’t change You may use the data fields in the struct and the functions provided in LL.h and LL.c. // reverses a linked list void LL_reverse(LL_t* list); Test for the Function; void test_q3() { LL_t* lst = LLcreate(); LL_add_to_tail(lst, 1); LL_add_to_tail(lst, 3); LL_add_to_tail(lst, 8); LL_add_to_tail(lst, 4); LL_add_to_tail(lst, 3); LL_reverse(lst); intcorrect[] = {3,4,8,3,1}; inti; node_t* n = lst->head; for(i=0;i<5;i++) { if (n==NULL) { printf("Q3 ERROR: node %d==NULL unexpected\n", i); return; } if (n->data != correct[i]) { printf("Q3 ERROR: node%d->data==%d, expected %d\n", i, n->data, correct[i]); return; } n = n->next; } if (n==NULL) printf("Q3 ok\n"); } Support File…

Write a program which should implement a linear linked list. Elements of this linked list should be of float type, user will provide values as input for elements of this linked list. Your program should allow deletion of a value of fist and last node of link list.
In this question, you are to implement two functions for reversing linked lists. One function, reverse_iter(..), must use an iterative approach (i.e., loops), whereas the other function, reverse_rec(..), must use recursion instead. We have already implemented the linked list as well as all its helper-functions in the Ilist-module.
Write a program which should implement a linear linked list. Elements of this linked list should be of integer type, user will provide values as input for elements of this linked list. Your program should allow searching of a value specified by user in linked list and display also it index.
For a singly linked list pointed at by pointer Ptr, write the implementation of a function named CountPositive that counts and prints the nodes with positive value in the list. Take in consideration all special cases. (** The declaration of the Node is: typedef struct Node { int data; Node*next; }Node;
Write a function, to be included in a sorted linked list class, called printPosition, that will receive a parameter and print its position within the list ( position 1 if first, position 2 if second...). If the item is not in the list, specify it in a printing. Consider efficiency.
write 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…
