How do you reverse a binary tree in Python?
How to Reverse a Binary Tree in Python
- class TreeNode: def __init__(self, x): self.val = x self.left = None self.right = None.
- def invertTree(node): if node is None: return None node.left, node.right = node.right, node.left invertTree(node.left) invertTree(node.right) return node.
Can you reverse a binary tree?
The key insight here is to realize that in order to invert a binary tree we only need to swap the children and recursively solve the two smaller sub-problems (same problem but for smaller input size) of left and right sub-tree. This looks similar to the idea of pre-order traversal.
Why would you reverse a binary tree?
Sometimes you’d rather change your existing data once than continue carrying forward what amounts to hacks, which is what inverting the output would amount to. Reversing a binary tree would be what you’d run in a tool to migrate all of your data over from the old format to the new format.
