Fun one :-)

I use a buffer around the 0 values & then spatial match (touch or intersect), to avoid problem when the missing value is located on the edge (even if not the case in this exercise)

Not sure if I made things harder for myself by not using the spatial tools, but I didn't see the value in this case.

Approach based on the below rough notes made when I first examined the problem:

This was a fun one, and not too tough. It had a little bit of spatial, a little bit of data prep, and a little bit of data reshaping!
