3.1 Cons Cell Representations

(a) Draw the list structure created by evaluating (cons 'A(cons 'B 'C)).

(b) Write a pure Lisp expression that will result in this representation, wotj mp sjaromg pf tje (B.C) cell. Explain why your expression produces this structure.

(c) Write a pure Lisp expression that will result in this represetnation, with sharing of the (B.C) cell. Expain why your expression produces this structure.

While writing your expressions, use only these Lisp constructs: lambda abstraction, function application, the atoms 'A 'B 'C, and the basic list functions (cons, car, cdr, atom, eq). Assume a simple-minded Lisp implementation that does not try to do any clever detection of common subexpressions or advanced memory allocation optimizations.
