The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. creATe a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition

Open Source for the Enterprise Open source software is changing the world of Information Technology. But making it work for your company is far more complicated than simply installing a copy of Linux. If you are serious about using open source to cut costs, accelerate development, and reduce vendor lock-in, you must institutionalize skills and creATe new ways of working. You must understand how open source is different from commercial software and what responsibilities and risks it brings. Open Source for the Enterprise is a sober guide to putting open source to work in the modern IT department.

A program to demonstrate the optimization process of ant colony optimization for the traveling saleman problem (TSP). The cities are shown as red circles, the pheromone on the connections between them (fully connected graph) by gray lines. The darker the grey, the more pheromone is currently on the edge. During the optimization, the currently best found tour is drawn in red. To run the optimization, first creATe a random TSP, then creATe an ant colony, and finally run the optimization.

SQL是英文Structured Query Language的缩写，意思为结构化查询语言。SQL语言的主要功能就是同各种数据库建立联系，进行沟通。按照ANSI(美国国家标准协会)的规定， SQL被作为关系型数据库管理系统的标准语言。SQL语句可以用来执行各种各样的操作，例如更新数据库中的数据，从数据库中提取数据等。目前，绝大多数流 行的关系型数据库管理系统，如Oracle, Sybase, Microsoft SQL Server, Access等都采用了SQL语言标准。虽然很多数据库都对SQL语句进行了再开发和扩展，但是包括Select, Insert, Update, Delete, creATe, 以及Drop在内的标准的SQL命令仍然可以被用来完成几乎所有的数据库操作。下面，我们就来详细介绍一下SQL语言的基本知识。

SQL(Structured Query Language，结构查询语言)是一个功能强大的数据库语言。SQL通常使用于数据库的通讯。ANSI（美国国家标准学会）声称，SQL是关系数据库管理系统的标准语言。SQL语句通常用于完成一些数据库的操作任务，比如在数据库中更新数据，或者从数据库中检索数据。使用SQL的常见关系数据库管理系统有：Oracle、 Sybase、 Microsoft SQL Server、 Access、 Ingres等等。虽然绝大多数的数据库系统使用SQL，但是它们同样有它们自立另外的专有扩展功能用于它们的系统。但是，标准的SQL命令，比如"Select"、 "Insert"、 "Update"、 "Delete"、 "creATe"和 "Drop"常常被用于完成绝大多数数据库的操作。
