Any one please correct this code it is not giving the result as expected.

Question

class image {
     public int[][] data;
     public int rows;
     public int columns;
public class BlurImage {
public int function1(image i1,int k,int j,int rad)

It should give the output as:------
test case 1:-
[ 11, 11, 11 ]
[ 10, 10, 10 ]
output.data = [ 10, 10, 10 ]
[ 9,    9,   9  ]
[ 9,    9,   9  ]
test case 2:-
[ 0x620058, 0x640055, 0x6a0050, 0x710048, 0x740044 ]
output.data = [ 0x620058, 0x640055, 0x6a0050, 0x710048, 0x740044 ]
[ 0x620058, 0x640055, 0x6a0050, 0x710048, 0x740044 ]

Answer 1

public class Test
     public static void main(String args[])
          throws Exception
          System.out.println("[ 10, 10, 10 ]");
}I'll let you customize the above code for test case 2.
There is not a single comment in the code. We have no idea what the code is supposed to do. We have no idea what you think is wrong. Therefore the above solution is the best we can provide.
