- 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 with the signature below that returns the sum of the last k elements of a singly linked list that contains integers. int returnSumOfLastKNodes(Node* head, int k) Example: 10 -> 5->8->15->11->9->23 10 represents the head node, returnSumOfLastKNodes(Node* head, 4) will return 58.Write a function set_elements() that assigns 1 to the last and fifth elements of a list parameter. Ex: If the input is: One man's trash is another man's treasure then the output is: ['One', "man's", 'trash', 'is', 1, "man's", 1] ''' Your code goes here ''' vals_to_update = input().split() set_elements(vals_to_update) print(vals_to_update)
- Write a driver function called size that takes as its parameter a linked list (nodeType pointer). The function should count how many nodes are in the list and return that value to the calling function.Write a functionLi stNode *removeFirst( ListNode *ptr)that is passed a linked list as parameter and returns the tai l of the list: That is, itremoves the first node and returns what is left. The function should deallocate thestorage of the removed node. The function returns null ptr if the list passed to itis empty.Ocaml Mode Write a function mode : ’a list -> ’a = that given a (nonempty) list it returns an element that repeats the most times (if ties exist, return the element among them that appears first in the list). examples mode [1;2;1;4;2;5;1;2;6];; - : int = 1 mode [’a’;’b’;’c’;’b’;’a’;’b’;’d’;’c’;’d’];; - : char = ’b’
- Write a function called myunion that will take two lists x and y, and return a list that has the elements of x, followed by the elements of y that are not found in x. For example: (myunion ’(1 3 5 7 9) ’(1 2 3 4 5 6 7)) should return (1 3 5 7 9 2 4 6).C Language In a linear linked list, write a function named changeFirstAndLast that swaps the node at the end of the list and the node at the beginning of the list. The function will take a list as a parameter and return the updated list.Create a function that takes the first Node in a linked list as an input, reverses the list (destructively), and then returns the original Node.
- You are given the pointer to the head node of a linked list and an integer to add to the list. Create a new node with the given integer. Insert this node at the tail of the linked list and return the head node of the linked list formed after inserting this new node. The given head pointer may be null, meaning that the initial list is empty. Function Description Complete the insertNodeAtTail function in the editor below. insertNodeAtTail has the following parameters: SinglyLinkedListNode pointer head: a reference to the head of a list int data: the data value for the node to insert Returns SinglyLinkedListNode pointer: reference to the head of the modified linked list Input Format The first line contains an integer , the number of elements in the linked list.The next lines contain an integer each, the value that needs to be inserted at tail. Constraints Sample Input STDIN Function ----- -------- 5 size of linked list n = 5 141 linked list data values…Please answer it in Python Write a function min_pair that takes a list as an argument and returns the smallest even integer contained in the list. If the list contains no even integers, the function will return None. Example: min_pairs([4, 7, 12, 0, 21, 5]) is 0 min_pairs([9, 3, 1]) is None. min_pair([16, 13, 10, 102, 7, 23]) is 10Imagine we have a linked list as shown below. The ListNodehas two fields: num, an integer, and next, a pointer to the next node. The list is not sorted. Write the definition of a function that calculates and returns the sum of the numbers in the list.
