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: Accepted)

import java.util.Scanner;

public class Main {
	public static void main(String[]args){
		Scanner sc=new Scanner(System.in);
		int n=sc.nextInt(),m=sc.nextInt(),l=sc.nextInt();
		long[][] A=new long[n][m],B=new long[m][l],C=new long[n][l];
		for(int i=0;i<n;i++){
			for(int j=0;j<m;j++){
				A[i][j]=sc.nextInt();
			}
		}
		for(int i=0;i<m;i++){
			for(int j=0;j<l;j++){
				B[i][j]=sc.nextInt();
			}
		}
		for(int i=0;i<n;i++){
			for(int j=0;j<l;j++){
				for(int k=0;k<m;k++){
					C[i][j]=C[i][j]+A[i][k]*B[k][j];
				}
				if(j==l-1){
					System.out.print(C[i][j]);
					System.out.println();
				}else
					System.out.print(C[i][j]+" ");
			}
		}
	}
