Can you find out a way through which you can make five squares out of the given figure by moving just six match sticks?
Four people need to cross a rickety bridge at night. Unfortunately, they have only one torch and the bridge is too dangerous to cross without one.

What is the shortest time needed for all four of them to cross the bridge?
