给定一个排序链表,删除所有重复的元素使得每个元素只留下一个.案例:给定 1->1->2,返回 1->2给定 1->1->2->3->3,返回 1->2->3详见:https://leetcode.com/problems/remove-duplicates-from-sorted-list/description/ Java实现: 递归实现: /** * Definition for singly-linked list. * public class…

Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example,Given input array A = […

Given a sorted array nums, remove the duplicates in-place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory.…

题意:从有序链表中删除重复节点. /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NULL) {} * }; */ class Solution { public: ListNode* deleteDuplicates(ListNode* head) { if(head == NULL || head…
