Hi All

Thanks a lot for all your suggestions and I have implemented 'summer cherry's logic.
Also, I tried to understand his logic, but not able to do so.

Could any one explain the below logic. I mean I know map and sort function, but don't know, how exactly below line will execute.

Quote:
print join "\n", map {$_->[1]} sort {$a->[0]<=>$b->[0]}map {my @tmp = split(",",$_); [$tmp[1],$tmp[0].",".$tmp[1]]} <DATA>;

With Regards,
Mysore Ganapati.
