If the last edge on the path from the rootrof a treeTto a nodexis (p,x), thenpis theparentofx, andxis achildofp. The root is the only node inTwith no parent. A node with no children is anexternal nodeorleaf. A nonleaf node is aninternal node ...
A node with no children is an external node or leaf. A nonleaf node is an internal node The number of children of a node x in a rooted tree T is called the degree of x. The length of the path from the root r to a node x is the depth of x in T. ...
