LeetCode: Reverse Linked List II Reverse a linked list from positionmton. Do it in-place and in one-pass. 这么一道小题做了一下午。。。真是太令我伤心了。 我的想法是 先找到开始反转的第一个元素的前面的那个元素,标记start。然后一边遍历 一边反转,最后前中后三段连在一起。 想法很简单,但是实现...
public class OneLinkNode { public int data; public OneLinkNode next; public OneLinkNode(int k) { data = k; next = null; } public OneLinkNode() { this(0); } public static void main(String args[]) { int n = 7; OneLinkNode head = create(n); insert(head, 3, 30); OneLinkNode p...
adding an element to the head is easy as it doesn't require a traversal till the end but if you want to create a list that contains elements in the order they are added then we need to add nodes at the end of the linked list. ...
