What is the method for reversing a linked list in golan…
In Golang, there are two methods to reverse a linked list: using iteration or recursion.
- Iterative method:
Iterative method is a technique of reversing a linked list by traversing it and changing the direction of pointers one by one. - A structure named ListNode has a value integer and a pointer to the next ListNode. A function reverseList takes in a head ListNode pointer and reverses the order of the linked list by changing the pointers accordingly.
- Recursion:
Recursion is a method that reverses the sub-lists of a linked list recursively, changing the pointers of adjacent nodes to achieve the reversal of the entire list. - A structure called ListNode is defined, which contains an integer value and a pointer to the next ListNode. A function called reverseList is implemented to reverse the sequence of nodes in a linked list.
It is necessary to handle the cases where the linked list is empty or has only one node, regardless of the method used, and always maintain a reference to the next node in the iterative approach.
