上面两种解法都是使用迭代的方法,此解法是使用递归的思路,先进入到链表的最后一位节点,然后反过来依次判断节点值是否相等,等于就跳到下一个节点,不等于就返回当前节点,来作为head的下一个节点。 publicListNoderemoveElements3(ListNode head,intval){if(head==null){returnnull;}head.next=removeElements3(head.next,...

When you remove an element, just do a doubly-linked list removal using the indices and push it to the free head. The iterator doesn't invalidate since it stores an index to a vector. When you insert, check if the free head is -1. If not, overwrite the node at that position and ...
