If there are n digits in a series and the span is exactly n, I’d think the largest product is simply the product of these n digits. If so, the error message
span must be smaller than string length
seems inaccurate. It should be:
span must be smaller than or equal to string length
Correct?
Correct. But possibly not worth correcting. See the doc below. The exception messages on the Python track and pretty arbitrary.
@Isaac - The exception messages on the Python track are not in the least arbitrary for practice exercises. They’re pulled directly from problem specifications, and are checked to match.
Ah. I missed that and ought to have realized that. My apologies.
Exception messages in the specs and in general are somewhat arbitrary. They typically are copy/pasted from the unit tests (from the file or from the test output).
