    Given a patient's medication profile with n potential drug interactions to analyze, determine the smallest block size (which must be a power of 2) that can accommodate all interactions for the hospital's drug analysis system. This block size ensures efficient processing of all possible medication combinations while minimizing computational resource waste.
