High-frequency trading systems frequently perform bulk risk checks against thousands of binary constraints, such as restricted instruments or permission flags. While standard containers offer convenience, custom bitset implementations utilizing 64-bit block processing and hardware intrinsics provide the necessary low-latency performance for these critical validation steps. This approach maximizes CPU throughput by processing multiple bits per instruction cycle. Task Implement a class DynamicBit
