How to solve this question?

Write a class LinkedList that holds a linked list of values. Your class should be in a source file named linked_list.py, and should support the following operations:

LinkedList(list) - create a LinkedList that initially holds the values in the given Python list

l.to_list() - return a Python list containing the values in this LinkedList

l.len() - return the number of nodes in a LinkedList

l.get(n) - return the value in the nth node, where nodes are numbered from 0. You may assume that 0 <= n < l.len().

l.has(x) - true if the list includes the value x

l.delete(x) - delete the first occurrence (if any) of the value x

l.rotate() - move the last node in the list to the head of the list; does nothing if the list is empty

l.starts_with(m) - true if the elements of the LinkedList m appear at the beginning of l

l.contains(m) - true if the elements of the LinkedList m appear in succession anywhere in l

l.ends_with(m) - true if the elements of the LinkedList m appear in succession at the end of l

Important: You may not use Python lists anywhere, except in the initializer and the to_list() method. Your LinkedList class may not store a Python list in any attribute. Also, generators (which we will study later in Programming 1) are not allowed in this assignment.

You do not need to read any input or write any output; simply submit a file linked_list.py containing the class described above.

Sample usage #1:

>>> l = LinkedList([2, 7, 4, 9, 18, 19, 22])
>>> l.to_list()
[2, 7, 4, 9, 18, 19, 22]
>>> l.len()
7
>>> l.get(3)
9
>>> l.has(17)
False
>>> o = LinkedList([7])
>>> o.to_list()
[7]
>>> o.len()
1
>>> e = LinkedList([])
>>> e.to_list()
[]
>>> e.len()
0
Sample usage #2:

>>> l = LinkedList([2, 7, 6, 4])
>>> l.delete(2)
>>> l.delete(5)
>>> l.delete(4)
>>> l.to_list()
[7, 6]
>>> l.delete(6)
>>> l.delete(7)
>>> l.to_list()
[]
>>> l.delete(8)
>>> l.to_list()
[]
