Hi,

Thanks for your help. But, I thought, I was not clear

in asking my question; sorry for that. I have arrays

of arrays and I want to compare each of the elements

of one array with the elements of the other array.

For example:

@data = (["A", "B", "C", "D", "E", "F", "G"],      ["A","C"],     ["B","F","G"],    ["A","D","E","F","G"], ["D","E","F"], ["G"], ["M", "N", "O"], ["O"], ["M", "N"], ; for $row ( 0 .. $#data ) { for $column ( 0 .. $#{$data[$row]} ) { print "$row $column is $data[$row][$column]\n";    } }

I understand till here how to access elements of

arrays of arrays.I would like to compare each of

the element in the array with the elements of the

next array,and depending upon the number of

matches, I would like to print it in the following

way. Any help in this regard would be

appreciated, as i am trying to get a clear concept

of arrays of arrays.

OUTPUT:

A B C D E F G

A D E F G

B E F

A C

G

M N O

M N

O
