Write a method intersection that takes two ranges

ruby-talk
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
(c) 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.

Hello,

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_?
