Your first attempt is correct but you need to change the @line_char to @line_words because you split the line and store all the characters into @line_words array only @line_char.One more suggestion whenever you do program, use the following in your code. 
use strict;
use warnings;

Both the modules help you to correct the problems in your program.If you use any scalar, array or hash without declaration,it will warn you.
