Reverse Linked List II Reverse a linked list from position m to n. Do it in-place and in one-pass. For example: Given 1->2->3->4->5->NULL, m = 2 and nreturn 1->4->3->2->5->NULL.
We assume that the target object is a singly linked list and implement code snippets accordingly. At first, we need to look at the basic function utilities in the driver code implemented to demonstrate the example. The linked list node is a simplestructwith a singlestringdata object and a po...
Let the linked list be 1->2->3->4->5->NULL (for simplicity in understanding representing pointer to node by node value) Head is 1 Initialize: cur =1, prev=NULL, next=NULL in iteration 1: next=2 cur->next=NULL prev=1 cur=2 thus reversed part: 1->NULL in iteration 2: next=3...
