Something I stumbled over today. If we have a series of bars of varying height, what's the largest rectangle that can be drawn over the bars without covering any empty space.
For example: '*'#"0~2 6 7 4 1 7 ** ****** ******* **** * ******* I'll post a solution later, and I'll be interested in seeing if it's basically the only obvious approach or if there's a variety of good approaches. (I have reason to believe, though, that there's a better way than what I came up with.)
