A typical implementation in Java or Kotlin assumes that a class that is used as a key implements the Comparable interface. To find a key, you have to compare the current node's key. If they are equal, then the root node is the result. If a key is greater than a current node's key, you have to move to a right node. Otherwise, you have to move to a left node.
It is built according to these rules:
- A binary tree has a root node.
- The left child node has a value that is less than the value of its parent nodes, and the right node has a value that is greater than the value of its parent nodes:
