【题目】
Given a linked list, reverse the nodes of a linked list k at a time and return its modified list.
If the number of nodes is not a multiple of k then left-out nodes in the end should remain as it is.
You may not alter the values in the nodes, only n...

题意：交换给定链表中的相邻节点,但不可以改变链表里的值
如1->2->3->4交换后为2->1->4->3
思路：
按题意中的扫描去改变每两个相邻节点的next指针的指向即可。
小技巧：
因为处理每两个相邻节点的时候，需要一个指针记录它们前一个节点，而头节点前面没有节点，
所以可设置一个dummy节点指向头指针，这样开头的两个节点的处理方式跟其它的相邻节点的处理方式就一样了
复杂度：时间O(n)，空间O(1)...
