Given a sorted linked list, delete all duplicates such this each element appear only once.For example,Given 1->1->2 , return 1->2 .Given 1->1->2->3->3 , return 1->2->3 .Ideas:More concise, traversing the linked list, encountering duplicate elements will delete the node. There is a note in the writing, the Link table node compares the node with the current node rather than the current node and the back node, there will be a more convenient writing proc

Follow up for "remove duplicates": What if duplicates are allowed at mostTwice? For example, given sorted array A =[1,1,1,2,2,3], Your function shocould return length =5, And a is now[1,1,2,2,3]. class Solution {public: int removeDuplicates(int A[], int n) { vector The first res element in key array A must be changed to the desired result.

Given a sorted Linked List, delete all duplicates such that each element appear onlyOnce. For example, Given 1-> 1-> 2, return 1-> 2. Given 1-> 1-> 2-> 3-> 3, return 1-> 2-> 3. Idea: The linked list is ordered. Each time you determine whether the current element is the same as the end element of the new linked list, if it is the same, it will be skipped; otherwise, it will be added to the end of the new linked list. 1 class solution {2 public: 3

Problem description: Given a sorted Linked List, delete all duplicates such that each element appear only once. for example, given 1-> 1-> 2 , return 1-> 2 . given 1-> 1-> 2-> 3-> 3 , return 1-> 2-> 3 . Train of Thought: For a traversal table, use two pointers to save the current position and the previous position of the current position. If the values of the two pointer nodes are equal, the current node is deleted. If not, the two point
