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)

matrix_A = []
matrix_B = []
matrix_C = []

n.times{
    matrix_A.push(gets.split.map(&:to_i))
}

m.times{
    matrix_B.push(gets.split.map(&:to_i))
}

n.times{|i|
    line = []
    l.times{|j|
        sum = 0
        m.times {|k|
            sum += matrix_A[i][k] * matrix_B[k][j]
        }
        line.push(sum)
    }
    matrix_C.push(line)
}


n.times{|i|
    puts(matrix_C[i].join(" "))
}
