How to find the maximum value in each branch of a tree and output their indexes as a tree?

[Leonard1]

Hello!

I am struggling to get the maximum value in each branch from one tree, and then output the indexes of those values as a tree. If there is no maximum value, then output ‘null’, as the pic shows.

Thanks for your help in advance!
