Questions & Step-by-Step Solutions

In which traversal method are nodes visited in the order of left subtree, root, right subtree?
  • Step 1: Understand that a tree has nodes, which can have left and right children.
  • Step 2: Know that there are different ways to visit or traverse these nodes.
  • Step 3: In one method, called In-order traversal, you first visit the left child of a node.
  • Step 4: After visiting the left child, you visit the node itself (the root).
  • Step 5: Finally, you visit the right child of the node.
  • Step 6: So, the order of visiting nodes in In-order traversal is: left subtree, root, right subtree.
