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?
