Consider the following function access_element_by_index that returns the iterator to the element at the index i in the list l. typedef std::list int_list; int_list::iterator access_element_by_index(size_t I, int_list &) { assert( ? ); … } Assume the first element of the list is at the index 0, the second at the index 1, and so on. If the function is required to return an iterator that can be dereferenced, determine the precondition of the function, and write an assertion to validate it. (You don’t need to implement the functions).

in C++ kth ElementExtend the class linkedListType by adding the following operations:a. Write a function that returns the info of the kth element of the linked list. If no such element exists, terminate the program.b. Write a function that deletes the kth element of the linked list. If no such element exists, terminate the program. Provide the deﬁnitions of these functions in the class linkedListType. please, do not copy from any other sources, give me a fresh new code. Thank you
Suppose a node of a doubly linked list is defined as follows: struct Node{ int data; struct Node* next; struct Node* prev; }; Write the function definition of the function deleteElement as presented below. This function deletes a node at position n from a doubly linked list. struct Node* deleteElement(struct Node* head, int n){ //write the function definition }
Please program in C 8.18 LAB: Simple linked list Given an IntNode struct and the operating functions for a linked list, complete the following functions to extend the functionality of the linked list: IntNode* IntNode_GetNth(IntNode* firstNode, int n)- Return a pointer to the nth node of the list starting at firstNode. void IntNode_PrintList(IntNode* firstNode) - Call IntNode_PrintNodeData() to output values of the list starting at firstNode. Do not add extra space characters in between values. int IntNode_SumList(IntNode* firstNode) - Return the sum of the values of all nodes starting at firstNode. Note: The code for IntNode_Create() provided here differs from the code shown in the book. The given main() performs various actions to test IntNode_GetNth(), IntNode_PrintList(), and IntNode_SumList(). main() reads 5 integers from a user: The number of nodes to be added to a new list The value of the first node of the list An increment between the values of two consecutive…

program by using C language In the struct structure given below, the data of a student is stored in a singly linear linked list. Write a function named "secondHighest" that takes the starting address of the list as a parameter and returns the student number with the second highest grade? typedef struct node { int OgrNo; int not; struct node *next; };
1. Suppose you have already developed an SLL ADT. You have to search a specificelement of the linked list. If you find the element in the list then you have to swapits previous node with its next node. Otherwise, simply print the message “Datanot found”. Now write a function in your SLL ADT with this functionality.
Suppose you have two objects of Doubly Linked List D1 and D2. Each object is representing a different Doubly Linked List. Write a function to concatenate both doubly linked lists. The concatenation function must return the address of head node of concatenated Doubly Linked List, and it must take two Node* parameters. You need to keep in mind all exceptional cases for example what if either one of the doubly linked lists is empty? Perform this task on paper, take a clear picture of solution and paste it in answer section.
Consider the following function that takes reference to head of a Doubly Linked List as parameter. Assume that anode of doubly linked list has previous pointer as prev and next pointer as next.void fun(struct node **head_ref){struct node *temp = NULL;struct node *current = *head_ref;while (current != NULL){temp = current->prev;current->prev = current->next;current->next = temp;current = current->prev;}if(temp != NULL )*head_ref = temp->prev;}Assume that reference of head of following doubly linked list is passed to above function 1 <--> 2 <--> 3 <--> 4 <--> 5 <-->6. What should be the modified linked list after the function call? Note: solve as soon as possible
Code in C : Data Structures , Linked List Objective: Implement programmer defined-data types with linked lists. Project name: SetList Make sure that the functions are tested in your main function.In case you can not implement all functions, ensure that there are no compile-time errors andthat there are no run-time errors for the completed functions. A set of integers may be implemented using a linked list.Implement the following functions given the definition:typedef struct node* nodeptr;typedef struct node{int data;nodeptr next;}Node;typedef Node* Set;Set initialize();- simply initialize to NULLvoid display(Set s);- display on the screen all valid elements of the listSet add(Set s, elem);- simply store elem in the listint contains(Set s, int elem);- search the array elements for the value elemSet getUnion(Set s1, Set s2);- get the union of s1 and s2 and return- x is an element of s1 union s2 if x is an element of s1 or x is an element of s2Set intersection(Set s1, Set s2);- get the…
Write a function inde which returns the index (start from 1) of the occurrence of a given value. Use helper function. Two functions are enough.inde(1, [1,2,1,1,2,2,1]) → [1,3,4,7] Write a function nele which repeats each element in a list n times. Use helper function. Two functions only.nele([1,2],3) → [1,1,1,2,2,2] Write a function isfact to determine if a positive integer is a factorial number. Do not use any formula such as T(n)=n(n+1)/2. Do it in recursive fashion. Two functions are enough.isfact(120) → true
The following C function takes a single-linked list of integers as a parameter and rearranges the elements of the list. The function is called with the list containing the integers 1, 2, 3, 4, 5, 6, 7 in the given order. What will be the contents of the list after the function completes execution? struct node { int value; struct node *next; }; void rearrange(struct node *list) { struct node *p, * q; int temp; if ((!list) || !list->next) return; p = list; q = list->next; while(q) { temp = p->value; p->value = q->value; q->value = temp; p = q->next; q = p?p->next:0; } } a) 1, 2, 3, 4, 5, 6, 7b) 2, 1, 4, 3, 6, 5, 7c) 1, 3, 2, 5, 4, 7, 6d) 2, 3, 4, 5, 6, 7, 1
