Pandigital Number.cpp

/*
This Program Check weather the Given Input (number) is Pandigital Number or Not.

If a number contains each of the digits from 0 to 9 at least once (0 not being the leading digit), it is considered to be Pandigital Number.

For example:
 1076398452 is Pandigital.
 11145689723232309899 is also Pandigital.
