Right image, but under those each one below would also be wearing large pants covering each side of the subtree.
A binary tree matryoshka
The first one is clearly wrong because no-one (oh alright, almost no-one, Toe-Jeans Georg) wears leg-wear on our toes.
Third option: The top layers are covered by a poncho and only the eight pairs at the bottom have leg-wear. This works when considering each subtree as a separate tree in its own right, up to arguing about how many ponchos are then required.
Fourth option: The top two branches wear leg-wear and those below go in footwear of some sort.
Those are trousers.
Depends on the side of the Atlantic on which one resides
The family pant.
Look at this guy not putting on pants because HIS last branch (toes) prevents him. You think the cops will believe that story?
