**Problem 755**(View Problem). For instance, consider S(1). On the one hand, we know f(0) = 1, so S(1) >= 1. However, if we consider the lone Fibonacci term "1" an acceptable sum, then S(1) = 2.

So that's my question: does S(1) = 1 or 2? And by extension, can lone Fibonacci terms form sums? E.g., does f(13) count "13" as one of the sums?
