x=int(input())

# x*y矩阵
a=[]
for i in range(x):
    n=list(map(int,input().split()))
    a.append(n)
#print(a)

# y*z矩阵
b=[]
for i in range(y):
    m=list(map(int,input().split()))
    b.append(m)
#print(b)

#x:1-2  y:1-3  z:1-2
res=[[0]*z]*x  #res[i][j]=sum 出错，同时更新每行的第j个？？？？

for i in range(x):
    for j in range(z):
        sum=0
        for k in range(y):
            a1=a[i][k]
            b1=b[k][j]
            product=a1*b1
            sum += product
        print(sum,end=' ')
    print()
