``The Generalized U2-Flashlight Microsoft 5-Minute Puzzle'' By S. B. Ekhad and D. Zeilberger

Written: Sept. 29 1998.

When my wife, Jane Legrange, told me about this puzzle, I was humiliated by not being able to do it in five minutes. Then I consoled myself that my failure to do it is due to the fact that I am too wise (old?) to think locally. This paper presents the global solution, achieved with the aid of Shalosh.
