[snip] I recommend continuing to work on your statement of the problem until it is detailed, precise, and complete -- something along the lines of, "Given a set of sets, return a set of sets having the following properties: (1)... (2)..." This approach often brings to light logical problems in the loosely sketched requirements. It also produces the outline of a testing regimen to determine whether an implemented solution is correct. -- To email me, substitute nowhere->runbox, invalid->com.
