Question $38(14$ points$)$

Show the stack with all activation record instances, including static and dynamic chains, when execution reaches position $1$ in the following static$-$scoped program. The actual reference to a variable can be represented by a pair of Integers $($chain$\_$offset, local$\_$offset$).$ Give the pairs to each of the variables at position $1.$

You can draw the stack on a piece of paper, take a clear picture of your an$$wwer using your cell phone and then upload the picture.
