Cat Snuke is learning to write characters. Today, he practiced writing digits `1` and `9`, but he did it the other way around.

You are given a three-digit integer $n$ written by Snuke. Print the integer obtained by replacing each digit `1` with `9` and each digit `9` with `1` in $n$.

Input is given from Standard Input in the following format:

```
$n$
```

Print the integer obtained by replacing each occurrence of `1` with `9` and each occurrence of `9` with `1` in $n$.

-   $111 \leq n \leq 999$
-   $n$ is an integer consisting of digits `1` and `9`.

991

Replace the 9 in the ones place with 1, the 1 in the tens place with 9 and the 1 in the hundreds place with 9. The answer is 991.
