WebAdd two linked lists without using any extra space Given a linked list representation of two positive numbers, calculate and store their sum in a new list without extra space. For example, Input: X: 5 —> 7 —> 3 —> 4 —> null Y: 9 —> 4 —> 6 —> null Output: 6 —> 6 —> 8 —> 0 —> null (as 5734 + 946 = 6680) Practice this problem WebLinked list. In this article, we will see the introduction of linked list. Linked list is a linear data structure that includes a series of connected nodes. Linked list can be defined as the nodes that are randomly stored in the memory. A node in the linked list contains two parts, i.e., first is the data part and second is the address part.
