You are given a string $s$ consisting of two kinds of characters, `0` and `1`. Print the string obtained by replacing `0` with `1` and `1` with `0` in $s$.

The input is given from Standard Input in the following format:

```
$s$
```

Print the answer in a single line.

-   The length of $s$ is between $1$ and $10$, inclusive.
-   $s$ consists of two kinds of characters, `0` and `1`.

10

The 1-st character of s is 1, so the 1-st character to print is 0. The 2-nd character of s is 0, so the 2-nd character to print is 1.
