Merge two sorted linked lists and return it as a new list. The new list shoshould be made by splicing together the nodes of the first two lists. Solution: 1 /** 2 * Definition for singly-linked list. 3 * public class ListNode { 4 * int val; 5

Given a linked list, swap every two adjacent nodes and return its head. For example,Given1->2->3->4, You shoshould return the list2->1->4->3. Your algorithm shocould use only constant space. You may not modify the values in the list, only nodes

Given a sorted Linked List, delete all duplicates such that each element appear onlyOnce. For example,Given1->1->2, Return1->2.Given1->1->2->3->3, Return1->2->3. 1 /** 2 * Definition for singly-linked list. 3 * public class ListNode { 4 *

The simple recursive equation is as follows: F [I] = min {f [J] + sum [I]-sum [J]-(I-j) * X [J + 1]} And found that the complexity is too high At this time, we can see that it is a classic slope optimization. F [I] = min {f [J] + J * X [J + 1]-sum
