描 述: - Hint (can be made public later on): The visual representation that John perfers are spectograms.
Description: John and Sebastian are always arguing over one thing or another. This time round, John is of the opinion that a certain type of visual representation of files looks cooler while Sebastian argues that his favourite, QR Codes, look cooler. Unable to resolve this quarrel on their own, they went to their good friend Amaagah, who knew a fair bit about these topics. Amaagah, after giving it some thought, gave both of them a file which confused the two of them. Will you help John and Sebastian to settle their debate once and for all?
