Contract Killer 3

Revised date: 07/11/2012

Between us [company name] and you [customer name]

Summary:

We’ll always do our best to fulfil your needs and meet your expectations, but it’s important to have things written down so that we both know what’s what, who should do what and when, and what will happen if something goes wrong. In this contract you won’t find any complicated legal terms or long passages of unreadable text. We’ve no desire to trick you into signing something that you might later regret. What we do want is what’s best for both parties, now and in the future.

/**  
 *   Experimental problem solving with MongoDB
 * 
 *   描述： 
 *
 *     假设现在有百万级的数据，每个数据存储着用户的信息（可以是简易的信息），
 *     每个数据中含有一个用户的ID，还有一个特殊数据，我们可以将这个数据叫做“等级”。
 *     现在 我们的需求是：
 *       1，根据一个用户ID能快速找出该用户信息
 *       2，根据一个用户ID能快速找出比该用户的“等级”低的最靠近他的10名别的用户，和找出比该用户“等级”高的10名用户

-- 第一印象：使用 Haskell 计算排列组合这样轻而易举。

[ [a,b,c] | a <- [1..10], b <- [1..10], c <- [1..10] ]

[ [a,b,c] | a <- [1..10], b <- [1..a], c <- [1..b] ]

[ [a,b,c] | a <- "abc", b <- "abc", c <- "abc" ]
