To check if a binary tree is symmetric, we need to compare its left subtree and right subtree. To do this, we can traverse the tree recursively and compare the left and right subtrees at each level.

Witryna27 wrz 2024 · This is simple we just check if both left and right are None. def is_symmetric (node): return node.left is None and node.right is None assert is_symmetric (Node (None)) We get a tree with 3 nodes working. The simplest way to do this is to just check if left and right's value are the same ignoring if either are None.
