Assume that class ListNode is defined as follows: Python class ListNode: def __init__(self, value): self.value = value self._next = None

* a) [10 points] Write a function that checks if two linked lists contain a common value and briefly explain its time complexity. Python def CommonValue(root1, root2): # root1 and root2 are ListNode objects that reference roots of two different lists # Function should return True if the two lists include a ListNode with the same value. # CODE REQUIRED

* b) Write a function that checks if two sorted linked lists contain a common value and briefly explain its time complexity. Write the function such that its time complexity is as low as possible. Python def CommonValueSorted(root1, root2): # root1 and root2 are ListNode objects that reference roots of two different lists # Both lists are already in nondecreasing order # Function should return True if the two lists include a ListNode with the same value. # CODE REQUIRED
