Dynamic looping

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!
