Difference of Arrays

In this question, focus on understanding how to compute the difference between two arrays. You'll need to identify which elements are present in one array but not in the other, and vice versa. Pay attention to edge cases, such as when the arrays are of different lengths or when they contain duplicate elements. Be prepared to discuss the time and space complexity of your solution, as well as any potential optimizations you could implement. Finally, consider how you would handle this task in a real-world scenario, such as when dealing with large datasets.
