Is it possible for a person to function as a human ZIP/RAR data compressor? Memorize a small amount of data and then use an algorithm to extract it? Ok so I had a friend who stole the answer-key to a huge multiple-choice final exam, which took 3 hours to complete, and must have had hundreds of questions. So I said memorizing that many letters in a row, must be harder than the test itself. But he had a system. Where he could memorize a relatively small amount of data. Just a paragraph. And then he could plug that paragraph into an algorithimic formula, which would extract the full pattern of answers. In effect he was functioning as a human RAR. He was memorizing 40kbs of data but compressing it into 2kbs of data, and then using a formula to extract it. He was going through the same step by step process that WINRAR goes through when it takes the compressed data of an RAR file and then unpacks it. So is what my friend did actually possible? Is it really possible to be a human ZIP file?
