Bugs is hiding again. This time there are 9 caves arranged in a 3 by 3 grid. There are left-rightand up-down connections between caves, but not diagonal connections (so each corner cave has 2 connections to other caves, and the middle cave has 4 connections to other caves, etc.).(a) With 3 searchers, is it possible to come up with a strategy that will guarantee that you find Bugs?
