Re^2: Print/Lookup from array element to another array element
by Dr Manhattan (Beadle) on Apr 07, 2013 at 09:53 UTC

    Hi Loops

    I used the 'say' feature and it works correctly. My next question is- How do I lookup from one element in a array to another one?

    For instance the word "food" is a element in a hash. I want to lookup and if the combined elements of my array exists in the hash it should be printed

    I tried this-

        if (exists $hash{@array[3..$end]})
    {
        say @array[3..$end];
    }

      If you want to find one string inside another, just use index

      So, something along these lines :-

      my $text ='catfood';
# returns -1 if not found
say index($text,'food',0);

      The keys in a hash are always strings. You cannot use an array slice as a hash key. You have to join the list to form a string: 
          exists $hash{ join q(), @array[3 .. $end] }
