Format of the text file you’ll upload
It’s very important that you preserve the format of the text file you
submit for each part. We recommend simply editing part1.txt for
Homework 2.1, part2.txt for Homework 2.2, and part3.txt for Homework
2.3 and submitting that, with the questions still intact. You can delete
lines that start with #, or add lines that start with # for your own
comments if you really want to. The automatic grader will ignore all
lines that begin with #. However, if you leave the questions in place it
will make manual grading easier if that should become necessary for
some reason.
The lines that don’t begin with # are your answers. Every answer should
be a single line with no whitespace (the grader will remove all
whitespace before doing a string comparison, but if your answer has
whitespace in it it’s probably not the right answer). You should edit the
lines that don’t begin with # to put the answer there, there should be
no lines in the file that are not answers or comments/questions
(comments and homework questions begin with #).
There are only three kinds of answers:
• IP addresses, where you will replace N.N.N.N with a valid IPv4
address, such as 98.45.6.31
• MAC/hardware addresses, where you will
replace HH:HH:HH:HH:HH:HH with a valid MAC/hardware
address, like a4:50:4e:99:2d:55
• Other numbers, which contain only decimal digits and dots. For
these you’ll replace N with something like 1832 or 4.1.61
