It seems like the year of 2013 came only yesterday. Do you know a curious fact? The year of 2013 is the first year after the old 1987 with only distinct digits.

Now you are suggested to solve the following problem: given a year number, find the minimum year number which is strictly larger than the given one and has only distinct digits.
The single line contains integer *y* (1000 ≤ *y* ≤ 9000) — the year number.
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        int y = scanner.nextInt(); // Read the input year

        int nextDistinctYear = findNextDistinctYear(y); // Find the next distinct year

        System.out.println(nextDistinctYear); // Print the result
    }

    public static int findNextDistinctYear(int year) {
        while (true) {
            year++;
            String yearStr = Integer.toString(year);
            boolean hasDistinctDigits = true;

            for (int i = 0; i < yearStr.length(); i++) {
                for (int j = i + 1; j < yearStr.length(); j++) {
                    if (yearStr.charAt(i) == yearStr.charAt(j)) {
                        hasDistinctDigits = false;
                        break;
                    }
                }
                if (!hasDistinctDigits) break;
            }

            if (hasDistinctDigits) return year; //234
        }
    }
