Python program to search an element in a doubly linked list. In this program, we need to search a given node in a doubly linked list. To solve this problem, we will traverse through the list using a node current. Current points to head and start comparing searched node data with current node data. If…

Python program to remove duplicate elements from a Doubly Linked List. In this program, we will create a doubly linked list and remove the duplicate, if present, by traversing through the list. List after removing duplicates: In the above list, node2 is repeated thrice, and node 3 is repeated twice. Current will point to head,…

Python program to find the maximum and minimum value node from a doubly linked list. In this program, we will create a doubly linked list then, iterate through the list to find out the minimum and maximum node. We will maintain two variables min and max. Min will hold the minimum value node, and max…
