Ternary numeric notation is quite popular in Berland. To telegraph the ternary number the Borze alphabet is used. Digit 0 is transmitted as «.», 1 as «-.» and 2 as «--». You are to decode the Borze code, i.e. to find out the ternary number given its representation in Borze alphabet.

Input

The first line contains a number in Borze code. The length of the string is between 1 and 200 characters. It's guaranteed that the given string is a valid Borze code of some ternary number (this number can have leading zeroes).

Output

Output the decoded ternary number. It can have leading zeroes.

Examples

Input

.-.--


Output

012

Input

--.


Output

20

Input

-..-.--


Output

1012
s = input()

code = {'.':0, '-.':1, '--':2 }
idx = 0
ss = []
while True:
    if idx == len(s):
        break

    if s[idx] in code:
        ss.append(str((code[s[idx]])))
        idx += 1
    else:
        ss.append(str(code[s[idx:idx+2]]))
        idx += 2
print(''.join(ss))
