Hi ArifS,

Any suggestion?

Use Data::Dumper to look at @rows, you will see that you have an "array of arrays". How to access data structures like that is explained in perlreftut and perldsc.

BTW, your current code appears to be 95% copy-and-pasted from this article. That's not necessarily a bad thing but I recommend you additionally show your own efforts in solving the problem.
