$[11]$This problem has $2$ parts.

Note: If you are not able to do the first part, you are not prepared to take this class. If you find the second part extremely tricky, you will find the assignments for the course difficult and potentially more time consuming than you expect.

Part $1-$ Write a program that prints a range of lines from a text file. The program should take command line arguments of the form:

lrange $1020$ filename

will print lines $10$ through $20$ of the named file. If there are not enough lines in the file, the program should print what it can.

Part $2-$ Write a program called last$10$ that prints the last ten lines of a text file. The pro$-$ gram can be used from the command line with:

last$10$ filename or last$10$

If there is no filename, last$10$ processes standard input.
