You don't say why so it is difficult to advise how to fix the problem
you
are trying to solve using a variable.
To mimic the results you want, an example is below.
I hope this helps.

While this seems an easy way to scan the computation, its complexity is
O(N^2).
A more efficient linear solution is available either by using the
scanl/scanl1 templates of FXSL or by writing from scratch a recursive
named template.
