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.

自己编的扫雷的小程序，很用心的编写，对新手应该会有帮助。里面的小砖块、计数值显示都是小控件，以后有类似用途应该都用得上。控件以动态库的形式。(Own a small demining program, very hard to write, it should be helpful for the novice. Inside the small brick, the count display controls are small, after a similar purpose should all need them.)

控件自适应窗体，包括字体也都能自适应，方便简单(Fit your window!)
