task clarification
The use of the phrase natural numbers (according to Wikipedia)
(quoted from Wikipedia Natural number:
There is no universal agreement about whether to include zero in the set of natural numbers: some define the natural numbers to be the positive integers {1, 2, 3, ...}, while for others the term designates the non-negative integers {0, 1, 2, 3, ...}. The former definition is the traditional one, with the latter definition having first appeared in the 19th century.
I personally like positive integers or non-negative integers for one or the other; that way, there can be no misunderstanding. -- Gerard Schildberger (talk) 01:17, 21 February 2014 (UTC)
Of course, if all program examples would handle both cases, this would be a moot point. -- Gerard Schildberger (talk) 01:17, 21 February 2014 (UTC)
