UVaOJ442 这题看着好长,但意思就只一个,先输入一个数n,要输入表示矩阵的个数,然后输入矩阵,注意前面的字母可以是乱序的,然后跟着两个正数。输入完n个数后,就开始输入矩阵的组合,要求输出是这些组合的的参与元素计算的个数 若:A 没有和它乘的,元素没参与乘,那么就是0 (AB) 若A为105B为520,A的列数与B的行数相等,AB矩阵能相乘,那么乘的次数是 5*20*

这个题感觉类似于找BUG那个题,这个题给你很多运算式子,求解式子的值,主要就是括号问题。看了例题分析:感觉方法非常巧妙:利用了栈stack,:碰到一个字母就入栈,碰到一个右括号“)”,就出栈两个元素,计算后记录结果,并把结果再次入栈,以此类推,,好巧妙!也给我一个启示,像这种类似多括号问题,尽量试试stack分析解析式!!奥结构体构造函数初始化不能忘,构建新的结构体入栈很方便!#include #
