Given a sorted arraynums, remove the duplicates in-place such that each element appear onlyonceand 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. Example 1: Given nums=[1,1,2] Your ...
Given a sorted linked list, delete all nodes that have duplicate numbers, leaving onlydistinctnumbers from the original list. For example, Given1->2->3->3->4->4->5, return1->2->5. Given1->1->1->2->3, return2->3. 没什么太多讲的,能够使用递归和迭代两种方法来做,要细致考虑各种输...

今天力扣上的每日一题是「83. 删除排序链表中的重复元素」。 解题思路 题意:在一个有序链表中,链表中的值重复的节点仅保留一个。 重点:有序链表,所以,一个节点的值出现不止一次,那么它们必相邻。 下面使用两种方法 :递归,迭代。其中迭代又分为两种方法。
Remove Invalid Parentheses 【题目】Remove the minimum number of invalid parentheses in order to make the input string valid. Return all possible results. Note: The input string may contain letters other than the parentheses ( and ). Examples: 代码语言:javascript 代码运行次数:0 运行 复制 ...
