Added: Segregate list - odd and even based on data

Have an oddHead, oddTail, evenHead, evenTail
if element is even, add the the node to even list
similarly to odd list 
just append the even list to odd 
make evenTail->next=NULL as it would cause an infinite loop
corner cases NULL list, all Nodes are even, all nodes are odd etc..
