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: Wrong Answer)

using System.Text;
public partial class IntroductionToProgramming{
	public static void Main(){
		string[] line = System.Console.ReadLine().Split(' ');
		int n = int.Parse(line[0]);
		int m = int.Parse(line[1]);
		int l = int.Parse(line[2]);

		int[,] a = new int[n, m];
		int[,] b = new int[m, l];

		// ??????A?????????
		for (int i = 0; i < n; i++)
		{
			string[] line2 = System.Console.ReadLine().Split(' ');
			for (int j = 0; j < m; j++)
			{
				a[i, j] = int.Parse(line2[j]);
			}
		}
		// ??????B?????????
		for (int i = 0; i < m; i++)
		{
			string[] line2 = System.Console.ReadLine().Split(' ');
			for (int j = 0; j < l; j++)
			{
				b[i, j] = int.Parse(line2[j]);
			}
		}
		// ????????????C??????????????????
		for (int i = 0; i < n; i++)
		{
			StringBuilder sb = new StringBuilder();
			for (int j = 0; j < l; j++)
			{
				int c = 0;
				for (int k = 0; k < m; k++)
				{
					c += a[i, k] * b[k, j];
				}
				sb.Append(c.ToString() + " ");
			}
			System.Console.WriteLine(sb.ToString().Trim());
		}
	}
