Approach:
Merging Linked Lists:
First we traverse up to end of first linked list and assign next pointer of last node to head of second linked list
Sorting linked List:

1.append each element to a stack
2.sort them using sorted function
3.Now pop each element from stack one by one and start 
inserting poped element in to linked list from head

Python Code:

 def mergeResult(h1,h2):
    cur = h1
    while cur.next:
        cur = cur.next
    cur.next = h2
    lst = []
    cur = h1
    while cur:
        lst.append(cur.data)
        cur = cur.next
    lst = sorted(lst)
    cur = h1
    while cur and len(lst)>0:
        cur.data = lst.pop()
        cur = cur.next
    return h1
