You have an refrigerator with a small freezer compartment
capable of holding 7 ice cube trays stacked vertically.
But there are no shelves to separate the trays,
and if you stack one tray on top of another
before the ice cubes in the bottom tray are fully frozen,
the top tray will nestle into it, and you won't get full
cubes in the bottom tray.
You have an unlimited supply of trays,
each of which can make a dozen cubes.
What's the fastest way to make full-sized ice cubes?

把tray倒过来分隔
