Unique Digits Check

Given a non-negative integer (N), determine whether all digits in (N) are unique. A digit is considered unique if it appears exactly once in the number. For example, if (N = 123456789), then the output should be Unique, but if (N = 112233), then the output should be Not Unique.

The input is read from standard input (stdin) and the result is printed to standard output (stdout).
