Programming Exercise #4: Super fun edition

[Tolnaftate2004]

Today's challenge will include 2 problems:

1. hard Suppose that you are organizing housing accommodations for a group of four hundred university students. Space is limited and only one hundred of the students will receive places in the dormitory. To complicate matters, the Dean has provided you with a list of pairs of incompatible students, and requested that no pair from this list appear in your final choice.
   The point of this exercise is to GENERATE DISCUSSION. We are not asking you to WRITE the code, merely speculate as to how you might do it. BUT IF YOU FEEL COMPELLED, write the code to accomodate arbitrary lists from the Dean.
2. easy Solve this problem.

Note From Hell Raven: the 100 students are rooming in pairs of 2. So that is 50 pairs (I do not believe this was clear...)
