I have tried the following expression,

     $_=~s/^#.*$//;
     $_ =~ s/([^"|'](#)+.*[^"|'])\s*#.*$/$1/;
     $_ =~ s/[^"|']#.*[^"|']$//;

Desired output:
puts "Hello, Ruby!" ",,,,,....'''"
puts "############I don't want to remove this content bcoz it is in quotes#"
puts "This is for testing ##sdfsfsf"
puts 'This is for testing ##testing'
