83. Remove Duplicates from Sorted List
Submissions: 264227 Difficulty: Easy
题目意思:如今有一个已经排好顺序的链表,删除全部反复的节点。使每一个节点都仅仅出现一次!
Given a sorted linked list, delete all duplicates such that each element appear only once.
For example,
Given 1->1->2, return 1->2.
Given 1->1->2->3->3, return 1->2->3.
分析:
遍历链表。遍历过程中保存上一个节点的值假设与当前节点同样就删除
维护两个指针。一个指向前一个节点。一个指向当前节点,同样就运行删除操作
/**
* Definition for singly-linked list.
* struct ListNode {
* int val;
* ListNode *next;
* ListNode(int x) : val(x), next(NULL) {}
* };
*/ class Solution {
public:
ListNode* deleteDuplicates(ListNode* head) {
if(head==NULL)
return NULL;
ListNode* preNode=head;
ListNode* curNode=head->next;
ListNode* delNode=NULL;
while(curNode)
{
if(preNode->val==curNode->val)
{
preNode->next=curNode->next;
delNode=curNode;
curNode=curNode->next;
delete delNode;
delNode=NULL;
continue;
}
preNode=curNode;
curNode=curNode->next;
} return head;
}
};
