    Design an algorithm to determine the total number of possible ways to organize learning concepts into personalized curriculum modules, where each concept must be assigned to exactly one module and any number of modules can be created. Given n distinct learning concepts, calculate how many different valid module arrangements can be generated to accommodate diverse learning paths.
