Problem 4 [10pt] Consider a programming language that uses static scoping and the following subroutine nesting of functions A, B, C, D and E (e.g., D is defined in B, which is defined in A): 1. (5pt) Is it possible for function E to call function C given such subroutine nesting? If no, explain why if yes, explain how C's static link on the stack can be established. Make your explanation concise (in one or two sentences) 2. (5pt) Is it possible for function C to call function E given such subroutine nesting? If no, explain why; if yes, explain how E's static link on the stack can be established. Make your explanation concise (in one or two sentences)
