Nettet11. jun. 2024 · In linked list problems, two pointers are often a great way to approach the algorithm. The idea behind two pointers is that when one reaches the end of a linked list, the other will be at an important point in the list (you can see another example of using two pointers in a linked list in this algorithm ). Nettet14. nov. 2024 · The first approach is to take a new linked list having n nodes, where n is the number of nodes of the original linked list. Then, we need to copy the traversed nodes to the new linked list in the same order. Algorithm Create an empty linked list. Initialize two pointers, one pointer pointing to the head and the other one pointing to the tail. Nettet1. feb. 2024 · Here we need to maintain a doubly linked list, with URLs as data field, to allow access in both direction.
