    Given n distinct health monitoring parameters for chronic disease patients, determine the number of different ways these parameters can be organized into monitoring schedules, where each parameter must be assigned to exactly one schedule and empty schedules are not allowed. Each unique arrangement of parameters across different monitoring schedules represents a valid partition, and the total number of such possible arrangements needs to be calculated.
