algorithmic modeling for Rhino

recombine different lists and preserving the order

Hi Guys

I'm driven by need to process a list and split negative from positive numbers to perform different actions on the 2 resulting sublists

After this i need to recombine the 2 lists but i want the items on the resulting list to get same index ( order )  they had before dispatch component , see list indicated with "V" for needed result ( just an example , no number processing in to this example )

I am just not able to remember how to combine the items togheter again

if anyone can help I appreciate , thanks

Ivan

You're looking for the [Sift] / [Combine] pattern.

(ignore the errors in the format components, that's a bug and unrelated.
