print " \s $arrayA[$i] \s $arrayB[$i] \s";

I have assumed that \s is giving space , so I just want , what should i replace $s with ?

    If that's what you want to print, you don't need any space regex.

    print " $arrayA[$x] $arrayB[$x] ";

    will print the spaces too...

    I hope that helps.

    If you use use strict; use warnings; you will probably find an error in this statement that has nothing to do with spaces. I suspect that you intend $i to be a subscript. If so,
    print " $arrayA[$i] $arrayB[$i] ";
    Note: \s is special character class for regular expressions. It does not have the same meaning in a string. Just use space characters.
