1. (4 pt) [Varlang programming, scoping] Write Varlang programs: (a) (1 pt) Compute the temperature in Kelvin given a temperature f = 58 in Fahrenheit. (b) (3 pt) Write a VarLang program that evaluates to value 34. The program must include at least 2 let expressions and there must be a "hole in one of the scopes". (The definition of this kind is seen in section 3.3 of Rajan-PL book pg 48), For example: (let ((x 2) (y 2)) (let ((x 27) (z 10)) (let ((z 20)) (- (* x y) z)))) $ 34 1.
