82. Remove Duplicates from Sorted List II Given a sorted linked list, delete all nodes that have duplicate numbers, leaving onlydistinctnumbers from the original list. Example 1: Input:1->2->3->3->4->4->5Output:1->2->5 Example 2: ...
083.remove-duplicates-from-sorted-list 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. # Definition for singly-linked list....
和有序数组原地消重一样,每次循环开始的时候,runner始终在walker前面(至少一步),所以不会产生数据覆盖。 小技巧: 新建一个头指针,作为walker的起始点,可以统一化操作 solution 1 /** * Definition for singly-linked list. * struct ListNode { * int val; ...
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. 题目解析: 这是一道非常简单的链表题目,题意是删除单链表(已排序)中的重复数字,只需一次判断前后两个结点数字是...
