Source sentences:
text: Nodes with two subtrees are called internal nodes, nodes without subtrees are called leaf nodes and nodes with only one subtree are named half-leaf nodes.
text: (Non-leaf children, rather than all children, are specified here because unlike normal binary search trees, red–black trees can have leaf nodes anywhere, which are actually the sentinel Nil, so that all nodes are either internal nodes with two children or leaf nodes with, by definition, zero children.
