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 C# (judge verdict: Accepted)

using System;

public class hello
{
    public static int n, m, L;
    public static int[,] a, b;
    public static void Main()
    {
        string[] line = Console.ReadLine().Trim().Split(' ');
        n = int.Parse(line[0]);
        m = int.Parse(line[1]);
        L = int.Parse(line[2]);
        a = getMatrix(n, m);
        b = getMatrix(m, L);
        getAns();
    }
    static void getAns()
    {
        for (int i = 0; i < n; i++)
        {
            var t = new long[L];
            for (int j = 0; j < L; j++)
                for (int k = 0; k < m; k++)
                    t[j] += (long)a[i, k] * b[k, j];
            Console.WriteLine(string.Join(" ", t));
        }
    }
    static int[,] getMatrix(int h, int w)
    {
        var ans = new int[h, w];
        for (int i = 0; i < h; i++)
        {
            string[] line = Console.ReadLine().Trim().Split(' ');
            for (int j = 0; j < w; j++) ans[i, j] = int.Parse(line[j]);
        }
        return ans;
    }
