7a. (3 pts). Draw an appropriate box/oval/arrow picture that illustrates the following computation. Label all boxes/variables with the name of the variable; label all ovals/objects with the name of its type. If a reference is changed, cross out the old reference and write in the new one. Assume all these definitions appear in module m, but you do not need to draw this module's object: just draw these name and their bindings. [1,2] x [0] X = x [1] y = x 7a. (3 pts).
