Problem 2320. Pandigital number n°2 (Inspired by Project Euler 32)

Created by Jean-Marie Sainthillier

Solve Later

After Problem 2319.
An n-digit number is pandigital if it makes use of all the digits 1 to n exactly ONCE.
For example, the 5-digit number 15234, is 1 through 5 pandigital.
Find the number of pandigital numbers in a given interval [xlower,xupper] (inclusive if it is not explicit enough).
The test suite is simple here, but how to compute this number with BIG interval (pandigital number length > 7) in Cody time?
For example, between 58755 and 99899923?

Instructions are incorrect. The instructions ask for pandigitals between the bounds, but at least the lower bound must be included to pass some of the tests.
