A pandigital number contains all digits (0-9) at least once. Write a function that takes an integer, returning true if the integer is pandigital, and false otherwise.

Examples

isPandigital(98140723568910) ➞ true

isPandigital(90864523148909) ➞ false
// 7 is missing.

isPandigital(112233445566778899) ➞ false

Notes

Think about the properties of a pandigital number when all duplicates are removed.
