# Problem C

Anagram Counting

An anagram is a reordering of the letters in a word of
phrase. For example, you can rearrange the letters of
`terraced` to get the word `retraced`. Rearranging them some more will give
you the word `cratered`. You can even
make `dactrere` and `redatrec`, which are both anagrams of `terraced` even if they are not legitimate
English words.

## Input

Input contains up to $200$ words, one per line. Each word consists of upper- and lower-case letters (a–z) and may have as many as $100$ characters. Input ends at end of file.

## Output

For every input word, output the total number of unique anagrams that can be made from it. For the purpose of this problem, upper- and lower-case letters are considered distinct.
