Discussion Starter mneha67 Discussion Starter mneha67 Need some help with this Array. I am trying to get the sum of the even numbers and the sum of the odd numbers using a for each loop. I know the answers to what I am trying to achive are sum of even = 84 and the sum of ...

i want to divide a matrix of n x m in smaller equal sized square matrix of size p x p..

pl help with this code.....

```
import java.util.Scanner;
class seg {
int seg[][] = new int[4][4];
}
class segment
{
public static void main(String args[])
{
int m, n, i, j = 0;
Scanner in = new Scanner(System.in);
System.out.println("Enter the number of rows and columns of matrix");
m = in.nextInt();
n = in.nextInt();
int matrix[][] = new int[m][n];
System.out.println("Enter the elements of matrix\n");
for ( i = 0 ; i < m ; i++ )
for ( j = 0 ; j < n ; j++ )
matrix[i][j] = in.nextInt();
System.out.println("entered matrix is:\n");
for ( i = 0 ; i < m ; i++ )
{
for ( j = 0 ; j < n ; j++ )
System.out.print(matrix[i][j]+"\t");
System.out.print("\n");
}
seg s[]=new seg[10];
int q, k=0,c=0,d=0;
if(c%(m+i)!=0 || d%(n+j)!=0)
{
for(i=c;i<c+4;i++)
{
for(j=d;j<d+4;j++)
if(i>=m || j>=n)
s[k++].seg[i][j]=0;//zero padding
else
s[k++].seg[i][j]=matrix[i][j];
}
c=c+4;
d=d+4;
}
System.out.println("segments are\n");
q=k;
do{
for ( i = 0 ; i < 4 ; i++ )
{
for ( j = 0 ; j < 4 ; j++ )
System.out.print(s[q--].seg[i][j]+"\t");
System.out.print("\n");
}
}while(q!=0);
}
}
```

You will have to elaborate the problem.

A simple 7x6 matrix is shown for example

S=

23 34 34 12 34 12

45 43 34 67 76 23

23 23 67 78 23 90

12 23 12 56 78 90

45 23 67 45 12 32

67 24 12 78 90 23

89 12 09 10 20 02

after dividing matrix into equal sized square matrix of size 4 x 4

I1=

23 34 34 12

45 43 43 67

23 23 67 78

12 23 12 56

I2=

45 23 67 45

67 24 12 78

89 12 09 10

00 00 00 00

I3=

34 12 00 00

76 23 00 00

23 90 00 00

78 90 00 00

I4=

12 32 00 00

90 23 00 00

20 02 00 00

00 00 00 00
