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 JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;
public class Main {

	public static void main(String[] args) {
		//??\???
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		int m = sc.nextInt();
		int l = sc.nextInt();
		int[][] A = new int[n][m];
		int[][] B = new int[m][l];
		int[][] C = new int[n][l];
		for (int ni=0; ni < n; ni++) {
			for (int mi=0; mi < m; mi++) {
				A[ni][mi] = sc.nextInt();
			}
		}
		for (int mi=0; mi < m; mi++) {
			for (int li=0; li < l; li++) {
				B[mi][li] = sc.nextInt();
			}
		}
		//?¨????
		for (int ni=0; ni < n; ni++) {
			for (int li=0; li < l; li++) {
				for (int mi=0; mi < m; mi++) {
					C[ni][li] += A[ni][mi] * B[mi][li];
				}
			}
		}
		//??????
		for (int ni=0; ni < n; ni++) {
			for (int li=0; li < l; li++) {
				System.out.print(C[ni][li]);
				if (li < l-1) {
					System.out.print(" ");
				}
			}
			System.out.println("");
		}
