comment Ordered subsets summation
@MarcvanLeeuwen. Thank you for the advise about $A=\{0,1,0\}$ instead of $A\{0,1,0\}$, once I'm a beginner studying math. Can I count also non-consecutive occurences of word $A$ in subsequence of another word $B$?

@HenningMakholm. It was my mistake. There are indeed 9 non-consecutive subsequences.

@celtschk, I want to count overlapping subsequences. I count 5 appearances of $A\{0,1,0\}$ in $B\{0,1,0,1,0\}$.

@hardmath, I want to count overlapping subsequences. I count 3 appearances of $A\{0,0\}$ in $B\{0,0,0\}$

Yes, @ArthurFischer. I'm looking for an algorithm.

@martini, I mean finite sequences. For instance, in $B\{0, 1, 2, 0, 1\}$, the ordered subset $A\{0,1\}$ appears twice. I'd like to count this.

Thanks, @Shaktal. What I need to know is that the cmp function is a signum function.

@KevinCarlson, This type of function $f_b(a)$ has a name? I'd like to read about. I'm not familiarized with mathematical terminology.
