Matches the nth child or odd and even element under its parent element: the EQ (index) match selector Specifies the elements of the sequence, and this will match the child elements for each parent element.: Nth-child starting from 1, and: Eq () is from 0! Available: To match the ordinal of an element, starting with 1Example Description:Find the 2nd Li in each ULHTML Code:JQuery Code:$("ul li:nth-child(2)")R

Find the nth node of the single-linked list to ensure that the minimum number of nodes in the list is N.Sample ExampleGiven the list 3->2->1->5->null and n = 2, the value of the second-to-last node is returned to 1.Analysis: Set two pointers P1 and p2,p1 traverse to n-1 position, P2 traverse from the beginning, when P1 to the tail of the list, p2 just to the bottom of the position of nAttention to robustness considerations/** * Definition of ListNode

Remove Nth Node from End of ListGiven A linked list, remove the nth node from the end of the list and return its head.ExampleGiven linked List:1->2->3->4->5->null, and n = 2.After removing the second node from the end, the linked list becomes 1->2->3->5->null.NoteThe minimum number of nodes in list is n.ChallengeO (N) timeSolution:Stupid method is to walk again, determine the length of the list, and then go

(i) The fast method for the nth term of the Fibonacci sequence F[n]=f[n-1]+f[n-2],f[1]=f[2]=1 (without considering the high accuracy).Solution:Consider the 1x2 matrix "f[n-2],f[n-1]". Based on the recursive relationship of the Fibonacci sequence, we want to get the matrix "f[n-1],f[n" = "f[n-1],f[n-1]+f[n-2" by multiplying a 2x2 matrix.It is easy to construct this 2x2 matrix A, namely: 0 1 1 1 So, th

Given A linked list, remove the nth node from the end of the list and return its head.For example, n = 2. After removing the second node from the end, the linked list becomes 1->2->3->5.Note:Given n would always be valid.Try to do the in one pass.Idea one: Take the entire link length l, then remove the L-n node.Idea two: Take two pointers, front and back,front precedence over the back n step, when front points to the last node, the backend points

First, the topicGiven a single linked list, delete the last nth node and return the deleted list.For example: known: 1->2->3->4->5, n = 2.After processing: 1->2->3->5. try to iterate through the completion.Second, analysisSee this question my first feeling is a double pointer, because to delete the number of the last nth, so the spacing of two pointers is this n, when the right hand pointer reaches the end,

Original title Link: https://oj.leetcode.com/problems/remove-nth-node-from-end-of-list/The problem is to remove the last nth node, by keeping 2 pointers, one fast and one slow, the quick pointer going first n, then the slow pointer going at the same time, until the fast pointer becomes null. This changes the value of the slow pointer to next. (Note that the slow pointer is actually a pointer to the cursor i
