主要算法 

• 矩阵置换
• 矩阵相乘

满分注意点

• 运算顺序，利用了矩阵运算法则中的（A*B）*c = A*(B*C)

# 矩阵置换
def zhihuan(a):b=[]for i in range(d):c = []for j in range(n):c.append(a[j][i])b.append(c)return b# 矩阵相乘

def dian_cheng(w,b):c,c_1=[],[]for i in range(len(w)):for j in range(len(b[0])):c_1.append(b[i][j] * w[i])c.append(c_1)c_1=[]return cn,d = list(map(int,input().split()))

list_k = [list(map(int,input().split())) for i in range(n)]
list_v = [list(map(int,input().split())) for i in range(n)]
