Write a method intersection that takes two ranges

Ruby
1

How do I write a method intersection(range1, range2) that takes two
ranges (a pair of start and stop coordinates on a line) and returns (a)
an array of subranges of range1 which are not contained in range2, (b)
an array of subranges of range2 that are not contained in range1, and
© the subrange common to both range1 and range2?

Thank you

These all sound like homework assignments and as a teacher I think you
should try these on your own first or you will learn nothing.

Do it on paper first, write every step. Then it would be easy to create
a 1st version that works :slight_smile:

Thank you

How about thinking of an algorithm yourself?
