In this post, we will see how to do matrix multiplication in C. If we want to multiply two matrices, then number of columns in first matrix must be equal to number of rows in second matrix. If this condition is not satisfied, below program will give you an error message. Here is sim...
JavaWeb之MVC思想(一) JavaWeb的MVC思想(一) 1.MVC模式。 M:Model(模型层)V:View(视图层)C:Controller(控制层) 控制层的作用: (1)根据用户的信息及逆行判断 (2)调用相应的模型 (3)将数据返回给视图层 2.三层架构 其中Service层和Dao层可以划分为模型层。 业务层,封装一些业务类。 业务:一个业务就是一...
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 orde...
The first line of the input file contains one integer n (1 <= n <= 26), representing the number of matrices in the first part. The next n lines each contain one capital letter, specifying the name of the matrix, and two integers, specifying the number of rows and columns of the mat...
栈的练习,如此水题竟然做了两个小时。。。 题意:给出矩阵大小和矩阵的运算顺序,判断能否相乘并求运算量。 我的算法很简单:比如(((DE)F)G)H)I),遇到 (就cnt累计加一,字母入栈,遇到)减一,并出栈两个矩阵计算运算量,将计算后的矩阵压入栈。当cnt等于0时就输出运算量。 难点...
