LeetCode第26题的边界条件有哪些需要注意? 题目描述 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) ...
在LeetCode第80题中,如何处理重复元素? 【原题】 Follow up for “Remove Duplicates”: What if duplicates are allowed at most twice? For example, Given sorted array nums = [1,1,1,2,2,3], Your function should return length = 5, with the first five elements of nums being 1, 1, 2, ...
Given input arraynums=[1,1,2], Your function should return length =2, with the first two elements ofnumsbeing1and2respectively. It doesn't matter what you leave beyond the new length. 思路: (1)虽然能AC,但是不对的思路:如果找到重复的数,就将其设置成一个很大的数,最后再排序一下,返回新的...

203. Remove Linked List Elements Given theheadof a linked list and an integerval, remove all the nodes of the linked list that hasNode.val == val, and returnthe new head. Example 1: Input:head = [1,2,6,3,4,5,6], val = 6Output:[1,2,3,4,5]...
Remove all elements from a linked list of integers that have valueval. Example Given:1 --> 2 --> 6 --> 3 --> 4 --> 5 --> 6,val= 6 Return:1 --> 2 --> 3 --> 4 --> 5 删除链表中指定的所有元素。 1)删除链表节点时应及时释放节点内存,以免内存泄漏。
Your function should return length = 2, with the first two elements of nums being 1 and 2 respectively. It doesn't matter what you leave beyond the new length. Try 1: 认为既然是sorted array,只用遍历一次array中的每个元素,判断该元素的前一个元素和该元素的后一个元素与该元素不相等即可。当相...
https://leetcode.com/problems/remove-linked-list-elements 和常规的删除一个node的情况不同的是,它要求删除所有val为指定值的node。 这道题要注意一个点: head node 的值是指定值,和中间node的值为指定值,在操作上不一样。比较好的办法是,在head前创建一个dummy node,那么这两种情况的操作就一样,最后返回...
