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.

极简网络聊天程序，，只需填上双方的计算机名或ip，以及使用的端口号即可。大小仅1.83k源代码总共17行，，呵呵，好玩极了！！！当填上192.168.0.255地址时，意味着你可以对局域网进行网络广播了-Minimalist Internet chat program, and the two sides need only provide the computer name or ip, and the use of the port can be. 1.83k size only source of a total of 17 firms, huh, and had a great time! ! ! When filling 192.168.0.255 address, which means you can pair of LAN network broadcast
