You can declare "local" variables in Racket via the use of the let function. For example, try the following code: (define a 2);;binding a variable to a value (define b 3) (define c 4) (define (strange x)     (let ((a 1) (b 2))       (+ x a b)))) After executing this code, what are the values of a, b, and c? What is the return value when you make the call (strange 4)? Explain your answers.
