_____________________________________________

A flashlight takes 2 (working) batteries.

There are 8 batteries (on the Table), but some of them may be Dead (and Non-Conducting).

To guarantee that the flashlight gets turned on, what is the minimum number of battery pairs you need to test ?

where D = (b - w)

flashlight(1, b, w) = D+1
