The reversal of a single-linked list is relatively simple, and iterative and recursive can be done.Define a class to represent the nodes in a single-linked list:public class ListNode {private int val;private listnode next;public listnode (int value) {this.val = Value;this.next = null; }public int Getval () {return val;} public void Setval (int val) {this.val = va
Divide the list into three sections, and then link the middle section reverse.The node position in the list is counted starting at 1.Note that M may be 1, so add if (last = = start) head = end; Otherwise, the data will be lost because the reverse head is the last node of the reverse section, and all the nodes before he
