Image Description

The Memory Diagram includes three columns titled Stack, Heap, and Output.

The Stack includes 4 frames in the following order from top to bottom including Globals, main, f, and g.

The Globals frame has 3 variables including f, g, and main.

f points to a function on the Heap (lines 1-2).
g points to a function on the Heap (lines 5-8).
main points to a function on the Heap (lines 11-12).

The main frame has 2 items including the RA and RV.

The RA is defined at line 16.
The RV is None.

The f frame has 3 items including the RA and RV and a variable named x.

The RA is defined at line 12.
The RV is 7.
x is “python”

The g frame has 4 items including the RA and RV and two variables named x and y.

The RA is defined at line 12.
The RV is 4
x is 4
Previous values of x include 7, 6, and 5 which are now crossed out * y is “java” The Heap includes 3 function objects. Output is empty.
