$1.(5$ points for code, $5$ points for explanation, $10$ points total$)$ A new language, Sonoma, with a

block structured syntax similar to Pascal uses either pass$-$by$-$reference or pass$-$by$-$value as a

parameter passing mechanism, but you don$$t know which. Design a test program you can use to

find out which parameter passing method it uses and explain how the results of your program

will enable you to detect the parameter passing mechanism. $($Do not be overly concerned about

the syntax of your code. Do not use example code from class.$)$
