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.

个人理财系统是我用MFC做的一个有界面的程序，里面涉及了数据库编程，常用的控件等知识。里面的数据都存储在SQL Server2005里面，我用的是ado方式访问数据库，实现了记录日常每餐的消费食物，消费水平，并可以自动算出一段时间的消费金额。(Personal financial management system is an interface program I do with MFC, which involves a database programming, controls and other knowledge. Inside the data stored in SQL Server 2005 which I use ado to access the database, to record daily meal consumption of food, consumption levels, and can automatically calculate the amount of the consumer for a period of time.)
