7 pair recursive (head, head2) This function takes two lists, which may be of different lengths (either or both of them might be empty). It builds new ListNode objects, where the value of each one is a tuple, consisting of one value from the first list, and one value from the second list, in the same order as they existed in those input lists. If the lists are different lengths, then the length of the returned list will be equal to the length of the shorter one. This function must be recursive, but is not required to obey the Annoying Requirements. 7.1 EXAMPLE Suppose that the input lists are as follows: -> head1: 123 -> 456 789 head2"abc" -> "def" -> "ghi" -> "jkl" then the list that you return must look like this: (123, "abc") -> (456,"def") -> (789,"ghi") 7.2 Recursing on Two Things So far, all of the recursive functions you've done have been over a single thing: either an integer, or a linked list. But there are some problems - like this one - where you recurse over two things in parallel. While this seems weird at first, if you look at it carefully, you'll realize it's not a lot more complex than what you've already done; in this problem you will pair the first value from list 1 with the first value from list 2, and then the second value from list 1 with the second value from list 2, an so on. So really, the only trick here is that when you recurse, you must recurse into the next field of both lists, at the same time
