##### Reference no: EM13698078

Program: Let c be an arbitrary SIMPL program and assume that judgment <c, {(x, 3)}> ßs' holds for some store s'. Prove by structural induction that x Î pre(s'), where pre(s') denotes the preimage of s'.

I looked up the definition of pre-image:

f: X®Y

x ? X is a pre-image of y ? Y if (y,x) ? ?  (? is a binary relation)

What should my recursive case be?
