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.
code = input()
k = []

s = ''

i = 0

while i < len(code):
    if code[i] == '-' and code[i+1] == '-':
        k.append(f'{2}')
        i+=2
    elif code[i] == '-' and code[i+1] == '.':
        k.append(f'{1}')
        i += 2
    else:
        k.append(f'{0}')
        i+=1


print(s.join(k))
