The problem is a person who uses this toothpaste-squeezing method has to go in for a dentist visit tomorrow, and he haven't even opened his tube of toothpaste. He figure if he can get 99% of the toothpaste on his toothbrush and brush with it, he will have shiny teeth. It's late at night and he doesn't want to have to squeeze the toothpaste tube more than neccesary.
A) What would be the best squeezing strategy if the tube had 3 zones? 4 zones?
B) Is there a best strategy that could apply for any number of zones?
