Questions & Step-by-Step Solutions

Which traversal method would you use to get the nodes of a binary tree in pre-order?
  • Step 1: Start at the root node of the binary tree.
  • Step 2: Visit the root node and record its value.
  • Step 3: Move to the left child of the root node.
  • Step 4: Repeat Step 2 for the left child (visit and record its value).
  • Step 5: If the left child has a left child, move to the left child and repeat Step 2.
  • Step 6: If there is no left child, move to the right child of the current node and repeat Step 2.
  • Step 7: Continue this process until all nodes in the tree have been visited.
