levelOrder

fun <T> ImmutableTreeNode<T>.levelOrder(): List<ImmutableTreeNode<T>>(source)

Returns this subtree's nodes in level-order (breadth-first: the receiver, then its children, then their children, and so on). Implemented iteratively, so it is safe on arbitrarily deep trees.

Return

the nodes of this subtree in breadth-first order, starting with the receiver.
