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)

import sys

input = sys.stdin.readline

def main():
    a, b, c = map(int, input().split())
    
    A = []
    
    for i in range(a):
        ai = list(map(int, input().split()))
        A.append(ai)
    B = []
    for i in range(b):
        bi = list(map(int, input().split()))
        B.append(bi)
    
    temp = 0
    for i in range(a):
        for k in range(c):
            temp = 0
            for m in range(b):
                temp += A[i][m] * B[m][k]
            print(temp, end ="")
            if k == c-1:
                print("")
            else:
                print(" ", end = "")
        
if __name__ == "__main__":
    main()
