Minimax
This program finds the maximum and minimum largest prime factors of the set of all zeroless pandigital numbers in base 10. This set looks like:
123456789
123456798
123456879
...
987654231
987654312
987654321
The program loops through all numbers between 123,456,789 and 987,654,321 inclusive, checks to see if they are pandigital, and then finds the largest prime factor of that number. If the largest prime factor is larger than any other previously recorded prime factor, it is saved as the maximum largest prime factor. If it is smaller than any previous largest prime factor, it is saved as the minimum largest prime factor. At the end, these two values are returned, along with the pandigital number to which they belong.
