Questions & Step-by-Step Solutions

What is the result of an inorder traversal of the binary tree with root 1, left child 2, and right child 3?
  • Step 1: Identify the root of the binary tree, which is 1.
  • Step 2: Look at the left child of the root, which is 2.
  • Step 3: Since we are doing an inorder traversal, we first visit the left child (2).
  • Step 4: After visiting the left child, we visit the root (1).
  • Step 5: Now, we look at the right child of the root, which is 3.
  • Step 6: Finally, we visit the right child (3).
  • Step 7: Combine the results from the visits: first we visited 2, then 1, and finally 3.
