TopicGiven A linked list, remove the nth node from the end of the list and return its head.For example, 1->2->3->4->5 N = 2. 1->2->3->5.Note:Given n would always be valid.Try to do the in one pass.AnswerUsing the idea of quick and slow pointers, the fast hands go first n steps, then go at the same time and stop at the end of the pointer. Note that the processing of the head node, such as 1->2->null, n=2, returns 2->NULL, the code is as follows:/*

Given A linked list, remove the nth node from the end of the list and return its head.For example,Given linked list:1->2->3->4->5, and 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.The usual solution is to rotation the total length of the list, calculate the index (LEN-N) that needs to be deleted, but it takes two cycles. The code is as follows:classS

Write a program to find the n -th ugly number.Ugly numbers is positive numbers whose prime factors only include 2, 3, 5 . For example, is the sequence of the first 1, 2, 3, 4, 5, 6, 8, 9, 10, 12 10 ugly numbers.Note that's 1 typically treated as an ugly number.Hint: The naive approach is to call for isUgly every number until you reach the nth one. Most numbers is not ugly. Try to focus your effort in generating only the ugly ones. An ugl

This method is used to precisely filter out the nth element on the basis of the selector, and the parameters are resolved as follows:1.index: An integer indicating that the element is based on a position of 0, and that the position of this element is calculated from 02.-index: An integer that indicates the position of the element, starting from the last element in the collection.

Find the nth element in the sequence (implemented by the partition function) and the partition Function Partition is a segmentation algorithm used to divide a sequence a [n] into three parts: a [n] is greater than the part of an element x, equal to the part of x and less than x. The Partition program is as follows: Long Partition (long a [], long p1, long p2) {// pair a [p1] ~ A [p2] splits and returns the number of the Split points. p1 and p2 are the

One-time Traversal Algorithm Algorithm The algorithm can be traversed only once. We can use two pointers instead of one. The first pointer moves n + 1 step forward from the beginning of the List, and the second pointer starts from the beginning of the list. Now, the two pointers are separated by N nodes. We keep this constant interval by moving the two pointers forward at the same time until the first pointer reaches the last node. The second Pointer Points to the
