zoj094 Matrix multiplication problem is a typical example of dynamical programming. Suppose you have to evaluate an expression like A*B*C*D*E where A,B,C,D and E are matrices. Since matrix multiplication is associative, the order in which multiplications are performed is arbitrary. However, the number of elementary multiplications needed strongly depends on the evaluation order you choose. For example, let A be a 50*10 matrix, B a 10*20 matrix and C a 20*5 matrix. There are two different strategies to compute A*B*C, namely (A*B)*C and A*(B*C). The first one takes 15000 elementary multiplications, but the second one only 3500. Your job is to write a program that determines the number of elementary multiplications needed for a given evaluation strategy.

这是一个基本的数据库编程实例,里面最特别的地方是即使出数据库里面出现多条完全相同的记录,它也能操作,而不会出错。(This is a basic database programming examples, there is the most special place inside the database even if there is more of the same record, which can operate without error.)

你将学到为何利用其他开发人员的经验与智慧解决问题，我们会看看设计模式的用途与优点，并通过实例来了解模式是如何运作。(You will learn why to use the experience and wisdom of other developers to solve the problem, we will look at the uses and benefits of design patterns, and an example to understand the model is how it works.)
