Given a sorted linked list, delete all duplicates such that each element appear onlyonce. Example 1: Input: 1->1->2 Output: 1->2 Example 2: Input: 1->1->2->3->3 Output: 1->2->3 很简单的链表问题,可以写成递归和迭代两种形式。具体思路: 第一步,寻找第一个节点值和当前表头所指的节...
Given a sorted linked list, delete all duplicates such that each element appear onlyonce. For example, Given1->1->2, return1->2. Given1->1->2->3->3, return1->2->3. 代码如下: 代码一,正常解法: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25...
从有序链表中删除重复的数字,并且返回删除后的头结点 例如输入链表为1->1->2,返回1->2 这题和leetcode26相似,只是数据结构从数组变成了链表 /** * @author rale * * Given a sorted linked list, delete all duplicates such that each element appear only once. * For example, * Given 1->1->2,...
1. File.Delete 方法在“指定的文件不存在”时引发 FileNotFoundException 异常。 2. File.Delete 方法在“指定的文件不存在”和“指定的路径无效”时不引发异常。 我更倾向于第二种方案。这样,在大多数情况下,就可以直接调用 File.Delete 方法,而不用先调用 File.Exists 方法。 续篇: Linux 操作系统下 File....
