len('1') < len('1') evaluates false, either order is correct in that case unless an extra rule for value order or something was added.

The tests generate two string with different length, so you always have one long string and one short string.

Chrono79, isn't the string of say one and two the same? Or "one" and "six".

What am I missing?

Thank you!

The strings will not be the same length
