Write a small program called callStackLastName in your language. In this program write $4$ methods named method$1(),$ method$2(),$ method$3()$ and method$4().$ These methods each have print statements indicating the name of the method. For example, method$1$ has the print statements $"$in method$1"$ and "exiting method$1".$ In the main method, include the a print statement $"$in main method" followed by calls to the various methods $($method$1,$ method$2,$ method$3,$ and method$4)$ and ending with the print statement "Exiting main".

Write a first version of the this and and play around with the program. Change the order of method calls and play some more.

Write $100$ words or more about what you observe with various runs. When does it enter and exit each method? What does that means in terms of what is happening in the call stackLinks to an external site.? This must reference the call stack, just describing the output does not tie it to the call stack.

Save your explanation as a $.$pdf file.
