Questions & Step-by-Step Solutions

What is the result of a level-order traversal on a binary tree with root 1, left child 2, and right child 3?
  • Step 1: Start at the root of the binary tree, which is node 1.
  • Step 2: Visit node 1 and record its value.
  • Step 3: Move to the next level and visit the left child of node 1, which is node 2.
  • Step 4: Visit node 2 and record its value.
  • Step 5: Move to the next node at the same level, which is the right child of node 1, node 3.
  • Step 6: Visit node 3 and record its value.
  • Step 7: All nodes have been visited, so the level-order traversal is complete.
