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.*;
 
public class Main {
  private static Scanner sc=new Scanner(System.in);;

public static void main(String args[]) {
    int n = sc.nextInt();
    int m = sc.nextInt();
    int l = sc.nextInt();
    long temp1[][] = new long[n][m];
    long  temp2[][] = new long[m][l];
    for (int i=0;i<n;i++) {
      for (int j=0;j<m;j++) {
        temp1[i][j] = sc.nextInt();
      }
    }
    for (int i=0;i<m;i++){
      for(int j=0;j<l;j++) {
        temp2[i][j]=sc.nextInt();
      }
    }
    for(int i=0;i<n;i++){
      for(int j=0;j<l;j++) {
        int ans=0;
        for (int k=0;k<m;k++) {
          ans+=temp1[i][k]*temp2[k][j];
        }
        System.out.printf(j==l-1?"%d%n":"%d ",ans);
      }
    }
  }
