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)

def dot(matrix1:[],matrix2:[])
    answer = Array.new(matrix1.size).map{Array.new(matrix2[0].size,0)}
    matrix1.size.times do |i|
        matrix2[0].size.times do |j|
            matrix2.size.times do |k|
                answer[i][j] += matrix1[i][k]*matrix2[k][j]
            end
        end
    end
    return answer
end

n,m,l = *gets.split.map(&:to_i)
matrix1 = []
matrix2 = []
n.times do
    matrix1.push(gets.split.map(&:to_i))
end
m.times do
    matrix2.push(gets.split.map(&:to_i))
end
answer = dot(matrix1:matrix1,matrix2:matrix2)
answer.each do |array|
    puts array.join(" ")
