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 Ruby (judge verdict: Accepted)

n, m, l = gets.split.map(&:to_i)
a = (0..n-1).map { gets.split.map(&:to_i) }
b = (0..m-1).map { gets.split.map(&:to_i) }
c = (0..n-1).map { (0..l-1).map { 0 } }
(0..n-1).each do |i|
  (0..l-1).each do |j|
    (0..m-1).each do |k|
      c[i][j] += a[i][k] * b[k][j]
    end
  end
end
c.each do |row|
  puts row * " "
end
