WebAug 16, 2024 · To add two numbers in a linked list, we can simply iterate the 2 linked lists and take the sum of the values in nodes along with maintaining a carry. While taking sums add the previous carry to it and add a new node to the result containing the last digit in the sum and update the carry for the next iteration. WebTo insert an element in a doubly linked list, we first need to create a list: class Nodeq: def __init__ (self, data): self.data = data. self.next = None. self.prev = None. There are three …
