 Given a linked list, swap every two adjacent nodes and return its head.
 
+You may not modify the values in the list's nodes, only nodes itself may be changed.

 Example:
 
+```c
 Given 1->2->3->4, you should return the list as 2->1->4->3.
-Note:

-Your algorithm should use only constant extra space.
