## March 2017 Fiendish Function

The Fiendish Function posed during March 2017 had the following sample guesses and replies:

- 1
- 5
- 2
- 5
- 3
- 4
- 4
- 4
- 5
- 4
- 10
- 5

The rule was: "Count the number of letters in the word for the number, then count the number of letters in the word for that number".

Suppose the guess was 17:

- Count the number of letters in "seventeen", giving 9.
- Count the number of letters in "nine", giving 4.

So the result is 4.
