Relaxed Atomic Stats Counter - Quant Developer Interview Question

Problem Description

Maintaining real-time statistics such as total volume or price high watermarks on the critical path requires extreme efficiency to avoid CPU pipeline stalls. Relaxed memory ordering in atomic operations minimizes synchronization overhead, allowing for thread-safe updates without the latency costs of standard mutexes or sequentially consistent atomics. This approach ensures that monitoring logic does not become a bottleneck in low-latency systems. Task Implement a thread-safe FastStats class to
