题目描述

删除链表中等于给定值 val 的所有节点。

示例:

输入: 1->2->6->3->4->5->6, val = 6
输出: 1->2->3->4->5

解题思路

创建一个新链表,遇到相同值的情况,将当前节点的next指向下一个节点的next,否则继续遍历。

var removeElements = function(head, val) {
    let dummyHead = new ListNode(); // 哑结点
    dummyHead.next = head;
    let p = dummyHead;
    while(p.next){
        if(p.next.val === val){
            p.next = p.next.next;
        }else{
            p = p.next;
        }
    }
    return dummyHead.next;
};
