Data for testing:

( 15pts) Write a code to return the median value in a sorted linked list. If the length i of the list is odd, then the median is the ceiling(i/2) member. For example, given the list (1,2,2,5,7,9,11) as input, your function should return the value 5 . If the length of the list is even, then the median is the mean of the i/2 and (i/2)+1 members. Thus, the median of the sorted list (2,4,8,9) is (4+8)/2. Finally, define the median of an empty list to be 0 . 100307506092901 102030405060708090
