Right image, but under those each one below would also be wearing large pants covering each side of the subtree.
What is the objectively correct answer. I have no idea why people keep asking that question.
A binary tree matryoshka
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?
It definitely wouldn’t be the left image. With legs like those, you could never pull the pants up past the first (or I guess technically last) level of branching. It would either be the big pants or a large number of seperate, smaller pants on each of the lowest branches.
Have you ever seen a binary tree grow? Maybe they put the pants on each level while it is the lowest one before the next level grows
If the pants are stretchy they could fit one of the lowest (already pantsd) branches in each leg of the jeans, and easily pull it up. You need bigger and stretchier pants as you go up the tree, though.
They could use pull-away pants that button up the back maybe
