Write a function that takes two call-by-reference arguments that are pointer variables that point to the heads of linked lists of values of type int. The two linked lists are assumed to be sorted so that the number at the head is the smallest number, the number in the next node is the next smallest, and so forth. The function returns a pointer to the head of a new linked list that contains all of the nodes in the original two lists.
