Questions & Step-by-Step Solutions

In a binary search tree, how does binary search help in finding an element?
  • Step 1: Start at the root of the binary search tree.
  • Step 2: Compare the value you are looking for (target) with the value of the root.
  • Step 3: If the target is equal to the root's value, you have found the element.
  • Step 4: If the target is less than the root's value, move to the left child of the root.
  • Step 5: If the target is greater than the root's value, move to the right child of the root.
  • Step 6: Repeat steps 2 to 5 until you find the target or reach a leaf node (no children).
