Dynamic looping

[Kazimierz]

Hello KNIMErs,

I have a problem that could be shown as follows:

• Max number of elements: 4.
  It is dynamic value >1 set in th initial ‘Variable Creator’ node.

• Expected outcome: the following strings
  1 out of 4
  2 out of 4
  3 out of 4
  4 out of 4

  1 out of 3
  2 out of 3
  3 out of 3

  1 out of 2
  2 out of 2

where separating lines are for better visibility only.

With combination of ‘Counting Loop Start’ and ‘Variable Condition Loop End’

I’m able to get the first sub-set of expected outcome.

However, I’m not sure how to decrease the max number of elements by 1 and run the loop again, and again. What would you suggest?

Thank you in advance!

Thank you @rfeigel, your workflow is a solution to my challenge!

Hi there,
I would try to avoid double loops as they can get very slow if the number of iterations increases.

Maybe this one might help:

X out of Y

Hi @ActionAndi
Your workflow is really elegant, I like it, and - the most important - produces expected results.
Sorry for not marking your workflow as solution, but @rfeigel 's proposal produces expected results as well.

No worries! Next time I’ll be quicker

@ActionAndi thanks to your proposal, I have overcome another challenge!
I would give double-like to your post, if only that would be possible
