Low-latency trading systems often require highly optimized memory operations to minimize instruction cycles and maximize throughput. By implementing custom memory copy routines that utilize wider register moves, developers can simulate SIMD-like behavior and reduce function call overhead found in generic standard library implementations. This problem explores manual memory optimization techniques essential for high-performance financial infrastructure. Task Implement the customMemcpy method in
