Choose and Match a number with a segment.

[t123x]

Hello,

I have a list of vertical numbers that gets placed in segments
eg.
#=Segment
11-27=7

8-10=6

4-5=4

2-3=3

In the solution cell, I would like to match a number automatically with a segment, how do I do that?

eg. if cell C39 = 11 (which is the #)
Then I would like C41 = 7 (which is the segment)

I have attached a sample, and the highlighted area is where I would like to plug the equation instead of manually selcting.

Thanks!
