Implement a custom memcpy function, including handling memory overlapping.

AI-Expanded — inferred from the question title, not from the original candidate report

Implement a function `my_memcpy(void *dest, const void *src, size_t n)` that copies `n` bytes from a source memory block to a destination memory block. Your implementation must correctly handle cases where the source and destination memory regions overlap by ensuring that data is not overwritten before it is copied.
