When it is required to rotate a doubly linked list by a specific number of nodes, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node:    def __init__(self, my_data):       self.previous = None       self.data = my_data       self.next = None class double_list:    def __init__(self):       self.head = ...

When it is required to remove the duplicate elements in a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node:    def __init__(self, my_data):       self.previous = None       self.data = my_data       self.next = None class double_list:    def __init__(self):       self.head = None   ...

When it is required to insert a new node in the middle of a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node:    def __init__(self, my_data):       self.previous = None       self.data = my_data       self.next = None class double_list:    def __init__(self):       self.head ...

When it is required to insert a new node at the end of a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node:    def __init__(self, my_data):       self.prev = None       self.data = my_data       self.next = None class double_list:    def __init__(self):       self.head ...

When it is required to insert a new node at the beginning of a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node:    def __init__(self, my_data):       self.prev = None       self.data = my_data       self.next = None class double_list:    def __init__(self):       self.head ...

When it is required to find the maximum and minimum values from a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node:    def __init__(self, my_data):       self.prev = None       self.data = my_data       self.next = None class double_list:    def __init__(self):       self.head = ...

When it is required to delete a node from the middle of a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Another class needs to be created that would have an initialization function, and the head of the node would be initialized to ‘None’ inside this.Multiple methods are defined by the user to add node to the linked list, to display the nodes ...
