具体的证明：点击打开链接 我的想法： 要想保证题目所说 构造最小行的和，仅仅能是这样的情况 ..... m-3 m-2 m-1 m | m m-1 m-2 m-3 . .... 所以Ans 也就是取前N项就可。 又由于 It is guaranteed that N is always odd。 显

没想到这个题目用一个剪枝和感觉上复杂度比较大的dp就可以过掉，当然这个题目的复杂度如果真仔细算起来感觉还是比较麻烦的，我在后面也提了几点设想，也许真正的复杂度没有到我们想象得那么大。
先把剪枝放在这里，设limit=min{max*min/(max-min)}，那么如果酒量是大于limit的，就必然能够全部装下，否则我们再执行dp。
下面我们开始证明这个

题目大意：
有n个瓶子，各有水量和容量。现在要将这写瓶子里的水存入最少的瓶子里。问你最少需要的瓶子数？在保证瓶子数最少的情况下，要求转移的水量最少。
解题分析：首先，最少的瓶子数肯定可以通过贪心来简单求解。然后就是将所有瓶子的水量作为01背包的总体积，然后就是$dp[i][j]$表示前$i$个物品选了水量为$j$的最大容量。本题的这种逆向思维有点像那道小偷抢银行的01背包

因为原先使用的c3p0链接池，时常出现：APPARENT DEADLOCK!!! Creating emergency threads for unassigned pending tasks，以及出现线程死锁的情况导致服务器经常需要重启，很是头疼。所以考虑使用Druid 链接池来代替原先的c3p0.Alibaba Druid中文文档依赖jar包：http://101.110.118.27/cen
