    Design a function for an adaptive learning platform that determines the minimum number of practice problems needed in the next difficulty level, where the number must be a power of 2 and at least equal to the current level's problem count. This adjustment ensures standardized assessment blocks while maintaining the platform's progressive difficulty scaling.
