ANSWER THAT MCQ QUESTION IN 2 MINUTES PLEASE..
The following function reverse() is supposed to reverse a singly linked list. There is one line missing at the end of the function.
/* Link list node */
struct node { int data; struct node* next; };
/* head_ref is a double pointer which points to head (or start) pointer of linked list */
static void reverse(struct node** head_ref) { struct node* prev = NULL;
struct node* current = *head_ref; struct node* next;
while (current != NULL) { next = current->next;
current->next = prev;
prev = current;
current = next;
} /*ADD A STATEMENT HERE*/ }
Trending now

Also, you need to implement the following functions: Insert Sorted LINKEDLIST insertSorted(LINKEDLIST head, int num): head points to the first node in the sorted linked list; num is a number to be inserted in in correct place in the linked list pointed at “head”. The linked list should be sorted after inserting “num”. This function returns the head of the modified head. BSTREE insert(BSTREE root, int num): root points to a node in a binary search tree; num is a number to be inserted in the tree rooted at “root”. This function returns the root of the modified tree. Find an element LINKEDLIST find(LINKEDLIST head,int num): head points to the first node of a linked list; num is a number to be searched for in the linked list started at “head”.

- Write C code that implements a soccer team as a linked list. 1. Each node in the linkedlist should be a member of the team and should contain the following information: What position they play whether they are the captain or not Their pay 2. Write a function that adds a new members to this linkedlist at the end of the list.Use C++ Programming language: Design and implement your own linked list class to hold a sorted list of integers in ascending order. The class should have member functions for inserting an item in the list (in ascending order), deleting an item from the list, and searching the list for an item. Note: the search function should return the position of the item in the list (first item at position 0) and -1 if not found. In addition, it should have member functions to display the list, check if the list is empty, and return the length of the list. Be sure to have a class constructor a class destructor, and a class copy constructor for deep copy. Demonstrate your class with a driver program (be sure to include the following cases: insertion at the beginning, end (note that the list should alway insert in ascending order. However, in your test include a case where the inserted item goes at the beginning of the list), and inside the list, deletion of first item, last item, and an item…True/False Select true or false for the statements below. Explain your answers if you like to receive partial credit. 3) Which of the following is true about the insertBeforeCurrent function for a CircularLinked List (CLL) like you did in programming exercise 1?a. If the CLL is empty, you need to create the new node, set it to current, andhave its next pointer refer to itselfb. The worst case performance of the function is O(n)c. If you insert a new element with the same data value as the current node, theperformance improves to O(log n)
