Interval order question.

  If I enter the pair (34, 17), your program changes it to the interval (17,
  34). Because the pair, as entered, (i.e. a=34 and b=17) violates the a<=b
  relationship, why doesn't your program print an error message?

The first sentence of the input section of the assignment is "Input is a
sequence of integers; consecutive pairs of integers are the endpoints for an
interval." In other words, input is not intervals, but interval endpoints. By
themselves, there's no order requirement on interval endpoints; order only
matters when they combine form an interval.
