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.


-----Input-----

The single line contains integer y (1000 ≤ y ≤ 9000) — the year number.


-----Output-----

Print a single integer — the minimum year number that is strictly larger than y and all it's digits are distinct. It is guaranteed that the answer exists.


-----Examples-----
Input
1987

Output
2013

Input
2013

Output
2014
