Lock-Free SPSC Ring Buffer - Quant Developer Interview Question

Problem Description

Low-latency financial systems rely on lock-free data structures to minimize thread contention and context switching during market data streaming or order execution. The Single-Producer Single-Consumer (SPSC) ring buffer utilizes atomic indices and memory barriers to ensure thread safety without the overhead of mutexes. This approach maximizes throughput in high-frequency trading environments where microsecond delays are critical. Task Implement the SPSCQueue class in C++17 to manage a fixed-siz
