6-The following are design issues for subprograms. Explain the design choices in python for these issues. Please also provide enough examples to illustrate the design choices. • Are local variables statically or dynamically allocated? • Can subprogram definitions appear in other subprogram definitions? • What parameter-passing method or methods are used? • Are the types of the actual parameters checked against the types of the formal parameters? • If subprograms can be passed as parameters and subprograms can be nested, what is the referencing environment of a passed subprogram? • Can subprograms be overloaded? • Can subprograms be generic? • If the language allows nested subprograms, are closures supported?

Write the command that can be used to answer the following questions. (hint: try each out on the system to check your results.) a. find all files on the system that have the word test" as part of their filename. b. search the path variable for the pathname to the awk command. c. find all files in the /usr directory and subdirectories that are larger than 50 kilobytes in size. d. find all files in the /usr directory and subdirectories that are less than 70 kilobytes in size. e. find all files in the / directory and subdirectories that are symbolic links. f. find all files in the /var directory and subdirectories that were accessed less than 60 minutes ago. g. find all files in the /var directory and subdirectories that were accessed less than six days ago. h. find all files in the /home directory and subdirectories that are empty. i. find all files in the /etc directory and subdirectories that are owned by the group bin."
