Dear Monks,

Thanks to all for the replies. I could learn a thing or two about searching algorithms and complexities of algorithms through the replies. I figured out the easiest and quickest way would be to not use arrays at all. Instead I used hashes to store both lists. Then just did 'exists' on each of these hashes. Now the script completes in about 10 seconds.

Thanks,
