Question

Please answer all ten of the true or false?

O If you can get from a parent to a child using a reference, then you can get back to the parent using the same reference (i.e. there us an "undirected
edge" between a parent and child so you can go from parent to child).
O Leaves have no children and the root cannot be a leaf.
O The height of a node is the length of the path from that node to the root.
O K-ary trees (discussed in class) can be implemented using the "first child, next sibling" method (discussed in the book).
O A pre-order traversal visits children after processing the node itself.
O A post-order traversal visits children after processing the node itself.
O A binary tree has at most 1 child per node (it is binary: 0 or 1 children).
O Recursion can be used to determine the number of nodes in a tree.
O Recursion cannot be used to determine the height of a tree (iteration must be used).
O The textbook provides implementations for pre-, post-, and in-order tree iterators.
