def reverse_list (1st: List [Any], start: int, end: int) -> None: """Reverse the order of the items in list , between the indexes and (including the item at the index). If start or end are out of the list bounds, then raise an IndexError. The function must be implemented **recursively**. >>> lst ['2', '2', 'v', 'e'] >>>reverse_list (lst, 0, 3) >>> lst ['e', 'v', 'i', '2'] >>> lst [] >>>reverse_list (lst, 0, 0) >>> lst [0] >>> Ist = [] >>> reverse_list (lst, 0, 1) Traceback (most recent call last): IndexError #1 #1
Task 18: Add a function to task 1 which accepts a linear linked list List and converts it to a circular linked list. Where List is a pointer to the front of the list. Prototype of the function is as following Node *Convert( Node *List)
1-Let the list have a head and a tail. That is, a pointer (have a marker) to both the beginning (first Node) of the list and the last Node. What process does Tail facilitate? 2-insert(int index, int element): adds this element to the index position. For example, if index is 4, it adds this element between index 3 and 4 in the list. The size of the list has increased by one. 3-append(int elem): Adds the element to the end of the list. The size of the list has increased by one. 4-get(int index): Returns the element at the index position of the list, no change in the list. 5-remove(int index): Returns the element at the index position of the list. This element is removed from the list and the list size is reduced by one. 6-findMin(): returns the index of the smallest number in the list. 7-findMax(): returns the index of the largest number in the list. 8-search(int elem): searches elem in the list. It returns -1 when you can't find elem's index when you find it. 9-ToArray(): Return an…

Using C, Must be in C Create a menu driven program that performs the following tasks (each task is a menu item): a. Create a doubly linked list of length 5 using dynamic allocation. Your linked-list should support method Write a function on to print the content of the linked list following its order. Write a function on to reverse the doubly linked list. Write a function to Delete the first node in your doubly Linked list
25. An array-based implementation of an linked list a. requires less memory to store an item than a pointer-based implementation b. is not a good choice for a small list d. has items which explicitly point to the next items c. has a variable access time
Write the following function that partitions the list using the first element, called a pivot:def partition(lst): After the partition, the elements in the list are rearranged so that all the elements before the pivot are less than or equal to the pivot and the element after the pivot are greater than the pivot. The function also returns the index where the pivot is located in the new list. For example, suppose the list is [5, 2, 9, 3, 6, 8]. After the partition, the list becomes [3, 2, 5, 9, 6, 8]. Implement the function in a way that takes len(lst) comparisons. Write a test program that prompts the user to enter a list and displays the list after the partition.
Complete the reverse_list() function that returns a new string list containing all contents in the parameter but in reverse order. Ex: If the input list is: ['a', 'b', 'c'] then the returned list will be: ['c', 'b', 'a'] Note: Use a for loop. DO NOT use reverse() or reversed(). This is my code so far: def reverse_list(letters): for x in (letters): letters.sort(reverse=True) return lettersif __name__ == '__main__': ch = ['a', 'b', 'c'] print(reverse_list(ch)) # Should print ['c', 'b', 'a'] When submitting I get 4/10 and it says: Test input list ['a', 'b', 'c'] returns ['c', 'b', 'a'] Your output reverse_list() function reversed array incorrectly: ['c', 'b', 'a'] reverse_list() function should have returned: ['a', 'b', 'c'] Test input list ['a', 'b', 'c', 'd'], first element of returned list is ['d'] Your output First character of returned array should be a instead of d Test empty input array TypeError: object of type 'NoneType' has no len()
Which of the following statements regarding linked lists and arrays is correct? Group of answer choices: a. A dynamically resizable array makes insertions at the beginning of an array very efficient. b. Using a doubly linked list is more efficient than an array when accessing the ith element of a structure. c. A dynamically resizable array is another name for a linked list. d. Any type of list tends to be better than an array when there are a set number of maximum items known beforehand. e. If many deletions at any place in the structure were common, a linked list implementation would likely be preferable to an array
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.
