In autumn, leaves turn various shades of yellow, orange and red. Hornbeam saplings, stressed trees, and the lower branches of mature trees may exhibit marcescence—where leaves wither with autumn but abscission (leafdrop) is delayed until spring. [4] The smooth, gray trunk and larger branches of a mature tree exhibit a distinctive muscle-like ...

A binary tree is a rooted tree in which each node may have up to two children (the nodes directly below it in the tree), and those children are designated as being either left or right. It is sometimes convenient instead to consider extended binary trees in which each node is either an external node with zero children, or an internal node with ...
