I am supposed to create a unique array based on a non-unique one. Problem is that I am not supposed to use hashes of built-in modules (I know, I know, but it's for educational purposes!!).
What I thought I could do is to sort the array and then somehow, since the elements would be "next" to each other, remove the duplicates.
my @array_q3=(); #create the array to store all words in the file
open INFILE3, "<file";
while( my $line3 = <INFILE3>)
push @array_q3, $line3;
#sort the array so we can identify the duplicates
my @sorted_array_q3 = sort(@array_q3);
but my problem is that I can't understand how I can remove the duplicates now...
