B) True
C) True, but only for numeric lists/tuples
D) Depends on the size of the list/tuple
Step by step
Solved in 2 steps
- Insert and merge: Write a function insert_and_merge : (’a * int) list -> ’a * int -> (’ a * int) list = that takes a (’a * int) list, sorted in increasing order with respect to the first tuple value we call the key, and an element ’a * int. The function inserts the element at the appropriate position so the list remains sorted and outputs said list. Assume there are no duplicate keys and thus if the new element has the same key as another element in the list, the function sums their values instead. Sorting the list is not allowed. (in oCaml)struct node{int num;node *next, *before;};start 18 27 36 45 54 63 The above-linked list is made of nodes of the type struct ex. Your task is now to Write a complete function code to a. Find the sum of all the values of the node in the linked list. b. Print the values in the linked list in reverse order. Use a temporary pointer temp for a and b. i dont need a full code just the list partTopic: Singly Linked ListImplement the following functions in C++ program. Read the question carefully. (See attached photo for reference) int removeAt(int pos) Removes the number in the posth position of the list and returns the element removed. Performing removeAt(3) in the example list will remove the 3rd element of the linked list and the updated list will be: 10 -> 30 -> 50 When the value of pos is greater than the size or less than one, return -1. int removeAll(int num) Removes all instances of num in the linked list and returns the number of instances removed. In this list 10 -> 10 -> 20 -> 30 -> 10, performing removeAll(10) will remove all three 10's and the list will look like this: 20 -> 30. Then, it will return the number of instances removed, in this case, 3. int contains(int num) This will return the position of the first instance of the element num in the list. If num is not found, return 0. In the example, having the method contains(30) will…
- HELP 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.scheme: Q9: Sub All Write sub-all, which takes a list s, a list of old words, and a list of new words; the last two lists must be the same length. It returns a list with the elements of s, but with each word that occurs in the second argument replaced by the corresponding word of the third argument. You may use substitute in your solution. Assume that olds and news have no elements in common. (define (sub-all s olds news) 'YOUR-CODE-HERE )@6 The Reference-based Linked Lists: Select all of the following statements that are true. options: As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.
