Program 1: Java Program to Reverse a Linked List In this program, we will see how to reverse a linked list in java using the collections class. Algorithm: Start Declare a linked list of integer types without any initial size. Use the add method to add the elements. Append the elements a...
def reverseList(self, head): """ :type head: ListNode :rtype: ListNode """ dummy = ListNode(None) while head: # 终止条件是head=Null nextnode = head.next # nextnode是head后面的节点 head.next = dummy # dummy.next是Null,所以这样head.next就成为了Null ...

Here is our sample program to demonstrate how to reverse a linked list in Java. In order to reverse, I have first created a class calledSinglyLinkedList, which represents alinked list data structure. I have further implementedadd()andprint()method to add elements to the linked list and print...
