CSE MACHINE EXERCISES Using the CSE machine, evaluate the following two RPAL programs. Show the output of the program (if any), and the environment structure. 1. let sum n = n eq 0 -> 0 | n eq 1 -> 1 | (n * (n + 1) / 2) in Print (sum (30), sum (0), sum(1), sum (4)) 2. let F x y z = Istuple(x) -> (nil aug (x y) aug (x z) aug (x (y + 2 * z))) | Isstring(x) -> (x @Conc ItoS(y) @Conc ItoS(z)) | Print (x + y + z) in Print ( (F (1 , 2 , 4, 4) 2 1 ), (F 'COP-' 55 55), ( F 3 4 5))
