How to find highest points in random set and display them

[player49]

Hello people. I stuck with choosing the highest points from the incoming random set of points.
I sorted Z-values but cannot display my highest points.

Maybe you can help with that using basic components , not ghPython or C#

try to sorl the list of z values and take the highest value
than compare the two lists with > , and cull the pattern to separate the highest points
