Questions & Step-by-Step Solutions
What is the postorder traversal sequence of a binary tree with root A, left child B, and right child C?
Step 1: Identify the structure of the binary tree. The tree has a root node A, with a left child B and a right child C.
Step 2: Understand the postorder traversal method. In postorder traversal, we visit the left subtree first, then the right subtree, and finally the root node.
Step 3: Start with the left child B. Since B has no children, we can add B to the sequence.
Step 4: Next, move to the right child C. Since C also has no children, we can add C to the sequence.
Step 5: Finally, add the root node A to the sequence.
Step 6: Combine the results from steps 3, 4, and 5 to get the final postorder traversal sequence: B, C, A.
