 become familiar with trees;

Command line arguments
Both programs will read command line arguments. To read those we import the sys module and
process sys.argv, a list of strings whose rst element is the name of the module being interpreted,
whose second element is the rst command line argument, whose third element is the second command
line argument, etc. So if no command line argument is provided, then sys.argv is a list of length 1.
