It's a pity the test set does not include a case such that the largest running sum is not also the largest running product. Some solutions, including my solution of size 23, should fail because they take the sum, not the product.

I would suggest adding '9909911111' as a test case. That would weed out all people who took a shortcut by using a moving sum, instead of a moving product.
