Implement the memcpy function in C

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

Implement a function `void *my_memcpy(void *dest, const void *src, size_t n)` that copies `n` bytes from the memory area pointed to by `src` to the memory area pointed to by `dest`. Your implementation must handle potential pointer type casting correctly and ensure that the function returns a pointer to the destination memory block.

Context & Summary
