get tree width
class Node:
left = right = None
def node_only(iterable_nodes):
return filter(bool, iterable_nodes)
def iter_layer(layer):
layer = node_only(layer)
while layer:
yield layer
layer = node_only(node.left for node in layer) + node_only(node.right for node in layer)
def tree_width(root):
return max(map(len, iter_layer([root])) or [0])
