    Given a patient's time interval between hospital visits in days, determine if this interval can be represented as the difference between two squared numbers, which could indicate a potential cyclical pattern in their readmission history. For example, if a patient's visits are 7 days apart, we need to determine if there exist two positive integers whose squares, when subtracted, equal 7.
