Now I ask you, among these cows, what is the minimum difference between the heights of some cows and the height of a bookshelf?Analysis:Two methods: (1) 01 backpack, calculate the height of all

DescriptionFarmer John recently bought a bookshelf for Cow library, but the shelf was getting filled up quite quickly, and now the onl Y available space is at the top.Each of the N cows (1≤n≤20,000) have some height of Hi (1≤hi≤10,000) and a total height summed across all N cows of S. The bookshelf has a height of B (1≤b≤s To reach the top of the bookshelf taller

In fact, the bookshelf works well. You only need to calculate the location rectangle of the bookshelf in the ondraw () method of the custom gridview, and then the draw will be OK. I personally think it is relatively simple. The Code is as follows: Public class playbackfocusedgridview extends focusedgridview {Drawable minterlayer = This. getresources (). getdrawable (R. drawable. TV _playback_shelf); //

Now there is only space on the top shelf. In the N (1 ≤ n ≤ 20) Head ox, the height of the I head ox is hi (1 ≤ Hi ≤ 1,000,000 ). The shelving height is B (1 ≤ B ≤ 2,0

Poj 3628 bookshelf 2: http://poj.org/problem? Id = 3628 There is a bookshelf with a height of B. Now FJ has n cows, each of which has a height of hi. Now we pile up the cows so that the height of the heap is greater than or equal to B, the minimum height difference is required.
