Instructions

  1. Read through all  the provided source code to make sure that you understand the context. A  class named BinarySearchTree with an add method plus various utility  methods is provided for you. You must not change any  provided method with a body that is already complete. Note that linked  nodes are used to implement the BinarySearchTree class. Note also that  the data type allowed in the BinarySearchTree is constrained to be a  class that implements the Comparable interface and thus has a natural  total order defined.
  2. The min method of the BinarySearchTree class currently has no body. You must provide a correct body for the min method.
  3. A  sample main method is provided to illustrate building a simple binary  search tree and then using the min method to search for particular  values.

Problem Description: Finding the Minimum Value in a Binary Search Tree

Complete the body of the min method so that it returns the minimum value in the binary search tree.

The  following table lists an example call to min and the expected return  value when called in the context of the binary search tree pictured  below.

 

public class BSTMin {

  /** Provides an example. */

  public static void main(String[] args) {

    BinarySearchTree<Integer> iBst = new BinarySearchTree<>();

    iBst.add(10);

    iBst.add(12);

    iBst.add(8);

    iBst.add(2);

    iBst.add(6);

    iBst.add(4);

    Integer imin = iBst.min();

    // The following statement should print 2.

    System.out.println(imin);

    BinarySearchTree<String> sBst = new BinarySearchTree<>();

    sBst.add(“W”);

    sBst.add(“A”);

    sBst.add(“R”);

    sBst.add(“E”);

    sBst.add(“A”);

    sBst.add(“G”);

    sBst.add(“L”);

    sBst.add(“E”);

    String smin = sBst.min();

    // The following statement should print A.

    System.out.println(smin);

  }
