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_nm = Array.new(n).map{Array.new(m,0)}
b_ml = Array.new(m).map{Array.new(l,0)}
c_nl =Array.new(n).map{Array.new(l,0)}

for i in 0..n-1
   a_nm[i] = gets.split(" ").map(&:to_i)
end

for i in 0..m-1
   b_ml[i] = gets.split(" ").map(&:to_i)
end
for i in 0..n-1
    for j in 0..l-1
        #n????????????????¨????
        for k in 0..m-1
            c_nl[i][j] += a_nm[i][k] * b_ml[k][j]
        end
    end
end
c_nl.each{|x|
   puts  x.join(" ")
}
