Answer 1

OK，过了，是我之前想多了，其实更简单

代码如下：

import sys
s = sys.stdin.readlines()

n = int(s[0].strip())
matrixes = dict()
for i in range(1, n+1):
    name, row, col = s[i].strip().split()
    matrixes[name] = (int(row), int(col))

for i in range(n+1, len(s)):
    exp = s[i].strip()
    if exp == "": break
    if len(exp) == 1: print(0)
    else:
        ans = 0
        q = list()
        for i in exp:
            if i.isalpha(): q.append(list(matrixes[i]))
            elif i == ")":
                b = q.pop()
                a = q.pop()
                if a[1] == b[0]:
                    ans += a[0]*b[0]*b[1]
                    a[1] = b[1]
                    q.append(a)
                else:
                    print("error")
                    break
        else:
            print(ans)
