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 PHP (judge verdict: Accepted)

<?php
// Your code here!
    fscanf(STDIN,"%d %d %d",$A,$B,$C);
    // echo $A.$B.$C;
    
    for($i=0;$i<$A;$i++){
        $input_line1[] = array_map('intval',explode(" ",trim(fgets(STDIN))));
    }
    
    for($i=0;$i<$B;$i++){
        $input_line2[] = array_map('intval',explode(" ",trim(fgets(STDIN))));
    }
    
    $ans = "";
    foreach($input_line1 as $num_array1){
        $E=[];
        for($j=0;$j<$C;$j++){
            $D_ij =0;
            for($k=0;$k<$B;$k++)$D_ij+= $num_array1[$k]*$input_line2[$k][$j];
            $E[] = $D_ij;
        }
        $ans .= implode(' ',$E)."\n"; 
    }
    
    
    print $ans;
