LeetCode Top 100 Liked Questions 141. Linked List Cycle (Java版; Easy) 题目描述 Given a linked list, determine if it has a cycle in it. To represent a cycle in the given linked list, we use an integer pos which represents the position (0-indexed) in the linked list where tail conne...
dummyHead.next=null; }/**Get the value of the index-th node in the linked list. If the index is invalid, return -1.*/publicintget(intindex) {if(index < 0)return-1; ListNode cursor=dummyHead.next;inti = 0;while(cursor !=null) {if(i ==index)returncursor.val; i++; cursor=cur...
证明如下(证明参考:http://stackoverflow.com/questions/2936213/explain-how-finding-cycle-start-node-in-cycle-linked-list-work) 如上图所示,假设从链表起点到环的起点距离为m,从环的起点到p1和p2第一次相遇的地方距离为k,环的长度为n。设第一次相遇的时候p1走过了S步,则p2走过了2S步,所以 S = m + ...
Do not modifythe linked list. Example 1: Input:head = [3,2,0,-4], pos = 1Output:tail connects to node index 1Explanation:There is a cycle in the linked list, where tail connects to the second node. Example 2: Input:head = [1,2], pos = 0Output:tail connects to node index 0...
skipB- The number of nodes to skip ahead inlistB(starting from the head) to get to the intersected node. The judge will then create the linked structure based on these inputs and pass the two heads,headAandheadBto your program. If you correctly return the intersected node, then your ...
