Borze

### 题面描述 三进制数字符号在Berland很受欢迎。如果用borze编码表示电报的三进制数。数字 $0,1,2$ 分别被作为`.`，`-.`和`--`。你需要为borze编码解码。（把borze编码转换为三进制数）。 ### 输入格式 第一行包含在Borze编码。字符串的长度介于 $1$ 到 $200$ 个字符之间。这是保证给定的字符串是一个有效的一些三元数borze编码（这个数可能有前导零）。 ### 输出格式 一个三进制数（如果有前导零要输出）。

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.

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 the decoded ternary number. It can have leading zeroes.
