4 Soldiers, each with the time it takes them to get across
the bridge next to them. There is a hole in the bridge (that's that
cheap black spot on there), which is why ONE of the TWO soldiers
who may pass at a given time MUST carry the flashlight.
The soldiers must FULLY get across the bridge, since both must
have the flash light to look out for the hole.
The flashlight cannot be tossed or anything stupid like that.
It may be passed around on a side and be given to different soldiers on
a certain side of the bridge.
As long as you follow the rules, you may do as you wish.
(this was a complaint by one of my friends, who said he did not know
he had the option to do something).
Enjoy.
And please don't post the answer.
