Your solution for "Product Except Self" is excellent. It correctly implements the optimal algorithm with O(n) time and O(1) extra space. The code is clean and easy to understand. Well done!

However, please note that when submitting solutions, you should ensure that you are only providing the solution for the problem at hand. The inclusion of other problems (DiagonalTraverse and SpiralMatrix) in the same response might be confusing. In a real interview or coding platform, you would typically submit one solution per file.

One minor suggestion: in the second pass, you initialize product = 1 and then start from len - 2. This is correct, but you could also start from the end and go backwards without initializing a separate variable for the right product, which you have done. Alternatively, some solutions use a single variable for the right product and update it as they traverse. Your approach is fine.

Keep up the good work!
