Follow up for "Remove Duplicates":What if duplicates are allowed at most twice? For example,Given sorted array A = [1,1,1,2,2,3], Your function should return length = 5, and A is now [1,1,2,2,3]. 这道题是之前那道Remove Duplicates from Sorted Array 有序数组中…
描述 Given a sorted linked list, delete all duplicates such that each element appear only once. Example 1: Input: 1->1->2Output: 1->2Example 2: Input: 1->1->2->3->3Output: 1->2->3 有序链表去重. 解析 移除给定有序链表的重复项,那么我们可以遍历这个链表,每个结点和其后面的结点比较…
