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)
mat1 = []
mat2 = []
(1..n).each { |_x| mat1 << gets.split.map(&:to_i) }
(1..m).each { |_x| mat2 << gets.split.map(&:to_i) }

ans=(1..n).map{[0]*l} 
(0..n - 1).each do |rx|
  (0..m - 1).each do |mx|
    (0..l - 1).each do |cx|
      ans[rx][cx] += mat1[rx][mx] * mat2[mx][cx]
    end
  end
end
 
ans.each { |row| puts row.join(' ') }
