(Java) LeetCode 83. Remove Duplicates from Sorted List —— 删除排序链表中的重复元素 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...
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. 思路:定义两个指针,pre和cur,如果cur和pre相等,则cur移动;如果不相等,同时移动。 1 2 3 4 5 6 7 8 9 10 11 1...

Remove Duplicates from Sorted List II java编程算法 该文讲述了如何删除排序链表中的重复节点,并保留非重复节点。通过先构建一个虚拟头节点来处理头结点,然后遍历链表,如果当前节点和下一个节点的值相同,则删除当前节点,否则将当前节点和下一个节点连接起来。遍历结束后,返回虚拟头节点的下一个节点即可。该解法使用...
