PandigitalNumbers.java

/* 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 a pandigital. 
(Easy) -> Write a program to verify whether a given number is pandigital or not.
(Hard) -> In addition to verifying the number being pandigital, display the number of times each digit
appears in that number.
