Question 8. Write the following functions in Lisp. ONLY code written in Usp will be graded. 8a. Given a list, produce a list that is composed of the original list but cvery two consecuilive elements are swapped. E.B. (swap2 ' '(123.45)) would return (2.1435). (defun swap2(x) 8b. Given two lists, produce a list of pairs obtained from the original list. Assume that the entries of the lists are positive integers. If the number of entries does not match, use 1 as the corresponding pair. E.g. (pairup ' (12.34) " (1112.13.1415)) would return (1211)(212)(3.13)(4) 14) (115)). (defun pairup (xy)
