Face it, monkfan: one way or another, your examples as originally posted do not lead to a consistent description of the task -- they are not compatible with one another.

Please look them over carefully, figure out which example needs to be fixed, and update your post to clearly mark (not delete) the original example that was wrong; also provide a corrected version of that example, and mark it clearly as an update.

Otherwise, some of us will be inclined to downvote you.
