Remove Nth Node From End of List

Given a linked list, remove the nth node from the end of list and return its head.

For example,

   Given linked list: 1->2->3->4->5, and n = 2.

   After removing the second node from the end, the linked list becomes 1->2->3->5.


  • Given n will always be valid.
  • Try to do this in one pass.


要求只遍历一趟,只需要让两个指针p, q,p先走n步,然后p,q一起走,直到p到达链表结尾,此时q就是需要删除的节点.

You can’t perform that action at this time.
