WebJun 17, 2024 · Here you can see an example of a binary search tree: Binary search tree example. To find key 11 in this example, one would proceed as follows: Step 1: Compare search key 11 with root key 5. 11 is greater, so the search must continue in the right subtree. Step 2: Compare search key 11 with node key 9 (right child of 5). 11 is greater. WebOct 10, 2024 · Then depending on which way we go, that node has a left and a right and so on. 1. The left node is always smaller than its parent. 2. The right node is always greater than its parent. 3.
