Matrix Multiplication

Write a program which reads a $n \times m$ matrix $A$ and a $m \times l$ matrix $B$, and prints their product, a $n \times l$ matrix $C$. An element of matrix $C$ is obtained by the following formula:

\[
c_{ij} = \sum_{k=1}^m a_{ik}b_{kj}
\]

where $a_{ij}$, $b_{ij}$ and $c_{ij}$ are elements of $A$, $B$ and $C$ respectively.

Input

In the first line, three integers $n$, $m$ and $l$ are given separated by space characters

In the following lines, the $n \times m$ matrix $A$ and the $m \times l$ matrix $B$ are given.

Output

Print elements of the $n \times l$ matrix $C$ ($c_{ij}$). Print a single space character between adjacent elements.

Constraints

$1 \leq n, m, l \leq 100$

$0 \leq a_{ij}, b_{ij} \leq 10000$

Sample Input

3 2 3
1 2
0 3
4 5
1 2 1
0 3 2

Sample Output

1 8 5
0 9 6
4 23 14

Solution in Python3 (judge verdict: Accepted)

n, m, l = map(int, input().split())
a = [0 for i in range(n)]
b = [0 for i in range(m)]

for i in range(n):
  a[i] = list(map(int, input().split()))
for i in range(m):
  b[i] = list(map(int, input().split()))

s = 0
for i in range(n):
  for j in range(l):
    for k in range(m):
      s = s + a[i][k] * b[k][j]
    if k == (m-1):
      print(s, end="")
      s = 0
      if j == (l-1):
        print("")
      else:
        print("", "", end="")
