November 2016 Fiendish Function
The Fiendish Function posed during November 2016 had the following sample guesses and replies:
- 1
- 1
- 2
- 8
- 3
- 72
- 4
- 46
- 5
- 521
- 10
- 1
The rule was: "Cube the number, then reverse the order of the digits".
Suppose the guess was 13:
- Cube the number, giving 2197.
- Reverse the order of the digits, giving 7912.
So the result is 7912.
