- The specifications for the Sorted List ADT state that the item to bedeleted is in the list.1. Rewrite the specification for DeleteItem so that the listis unchanged if the item to be deleted is not in the list.2. Implement DeleteItem as specified in (a) using anarray-based implementation.3. Implement DeleteItem as specified in (a) using alinked implementation.4. Rewrite the specification for DeleteItem so that allcopies of the item to be deleted are removed if they exist.5. Implement DeleteItem as specified in (d) using anarray-based implementation.6. Implement DeleteItem as specified in (d) using alinked implementation.1. a function that takes in a list (L), and creates a copy of L. note: The function should return a pointer to the first element in the new L. [iteration and recursion]. 2. a function that takes in 2 sorted linked lists, and merges them into a single sorted list. note: This must be done in-place, and it must run in O(n+m).Implements clone which duplicates a list. Pay attention, because if there are sublists, they must be duplicated as well. Understand the implementation of the following function, which recursively displays the ids of each node in a list Develop your solution as follows: First copy the nodes of the current list (self) Create a new list with the copied nodes Loop through the nodes of the new list checking the value field If this field is also a list (use isinstance as in the show_ids function) then it calls clone on that list and substitutes the value. Complete the code: def L4(*args,**kwargs): class L4_class(L): def clone(self): def clone_node(node): return <... YOUR CODE HERE ...> r = <... YOUR CODE HERE...> return r return L4_class(*args,**kwargs)

A. if the array is initially in descending order B. if the array elements can be mapped to a linked list C. if the array elements are already close to their eventual sorted position D. if the array elements are string objects E. never, heapsort will always be fasterAssume that the values A through H are stored in a self-organizing list, initially in ascending order. Using the move-to-front heuristic and the table below, show the resulting list from the following series of accesses (note -- you only have to show the values in the last column of the table below): G H G H E C E H G A D C F Inputs List at Start G H G H E C E H G A D C F A B C D E F G HWrite an algorithm to implement the frequency count self-organizing list heuristic, assuming that the list is implemented using an array.

The operations that can be performed on the queue are: i. isEmpty (Q)– returns true if the queue is empty, false otherwise. ii. delete (Q) – deletes the element at the front of the queue and returns its value. iii. insert (Q, i) – inserts the integer i at the rear of the queue.
