Hi, here's your problem today. This problem was recently asked by Microsoft:
A k-ary tree is a tree with k-children, and a tree is symmetrical if the data of the left side of the tree is the same as the right side of the tree.
Here's an example of a symmetrical k-ary tree.
Given a k-ary tree, figure out if the tree is symmetrical.
Here is a starting point:

Here's an example of a symmetrical k-ary tree.
4
/ \
3 3
/ | \ / | \
9 4 1 1 4 9
Given a k-ary tree, figure out if the tree is symmetrical.
Here is a starting point:
class Node():
def __init__(self, value, children=[]):
self.value = value
self.children = children
def is_symmetric(root):
# Fill this in.
tree = Node(4)
tree.children = [Node(3), Node(3)]
tree.children[0].children = [Node(9), Node(4), Node(1)]
tree.children[1].children = [Node(1), Node(4), Node(9)]
print is_symmetric(tree)
# True
