Can't locate File/IO.pm in @INC
That error means that you told perl to load in the File::IO module, but it could not be found in the search path. Since your code doesn't seem to rely on that module anyway, try deleting the following line: 
use File::IO;

Please edit your post to use code tags for your code and error messages: Writeup Formatting Tips

To clean up other warnings and errors, change: 

$result_file = "C:\Users\spullabhotla\Desktop\TestToRemoveDuplicates.t
+xt";

to (my and single quotes): 
my $result_file = 'C:\Users\spullabhotla\Desktop\TestToRemoveDuplicate
+s.txt';

BTW, there is a Core module named IO::File, if that's what you are trying to use.
