IP多播
在局域网中,管理员常常需要将某条信息发送给一组用户。如果使用一对一的发送方法,虽然是可行的,但是过于麻烦,也常会出现漏发、错发。为了更有效的解决这种组通信问题,出现了一种多播技术(也常称为组播通信),它是基于IP层的通信技术(In a LAN, administrators often need to send a certain message to a group of users. If one to one transmission method is used, it is feasible, but it is too troublesome, and often there will be missed and wrong hair. In order to solve this kind of communication problem more effectively, there is a multicast technology (often called multicast communication). It is a communication technology based on the IP layer.)

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.
