Questions & Step-by-Step Solutions

What is the post-order traversal of a binary tree with root A, left child B, and right child C?
  • Step 1: Identify the root of the binary tree, which is A.
  • Step 2: Identify the left child of A, which is B.
  • Step 3: Identify the right child of A, which is C.
  • Step 4: In post-order traversal, first visit the left child (B).
  • Step 5: Next, visit the right child (C).
  • Step 6: Finally, visit the root (A).
  • Step 7: Combine the results from steps 4, 5, and 6 to get the final order: B, C, A.
