A perfect binary tree is a complete binary tree with all levels fully filled. Add a method in the BST class to return true if th

algol [13]

Answer:

class BST {

static class Node

{

int val;

Node left, right;

}

static boolean checkPerfectBT(Node node, int h, int d)

{

if (node == null)

return true;

if (node.left == null && node.right == null)

{

if(h==d+1)

return true;

else

return false;

}

if (node.left == null || node.right== null)

return false;

return checkPerfectBT(node.left, h, d+1) && checkPerfectBT(node.right, h, d+1);

}

static int height(Node node)

{

int dep = 0;

while (node != null)

{

node = node.right;

dep=dep+1;

}

return dep;

}

static boolean isPerfectBT(Node node)

{

int h = height(node);

return checkPerfectBT(node, h, 0);

}

static Node addNode(int x)

{

Node node = new Node();

node.val= x;

node.right = null;

node.left = null;

return node;

}

public static void main(String args[])

{

int i,j,k;

Node node= null;

node = addNode(34);

node.left = addNode(2);

node.right = addNode(322);

node.left.left = addNode(21);

node.left.right = addNode(23);

node.right.left = addNode(37);

node.right.right = addNode(54);

if (isPerfectBT(node) == true)

System.out.println("This is a Perfect Binary tree");

else

System.out.println("This is Not a perfect Binary Tree");

}

Explanation:

Calculate the depth of BST by using a while loop until it reaches a null value.
In the addNode method, make an object of Node class.
In the main method, pass the values to addNode method.
Finally display the relevant message to show if it's Perfect or not.

java class What is the output of the following JAVA program (Java assumes public if no access modifier is given)? class Test { p

Natasha2012 [34]

Answer:

The answer to the given question is it will produce an "error"

Explanation:

In the given java program it will produce an error because in java we do not use double quote("""") for message printing. We use a single quote("") for message printing. In the given program if we use a single quote(""). so it will give output that is "dogood:dogood".

The correct program to this question is can be given as:

Program:

public class Test //define a class test.

{

public static void main(String[] args) //define main method

{

Test obj = new Test(); //create class object

obj.start(); //calling function

}

void start() //define function start.

{

String stra = "do"; //define variable and assign value.

String strb = method(stra); //define variable and pass stra variable in method() function as a parameter.

System.out.print(":"+stra + strb); //print value.

}

String method(String stra) //define function method

{

stra = stra + "good"; //add value

System.out.print(stra); //print value of stra

return"good"; //return value

}

Output:

dogood:dogood

What is the nearest inhabited area to the amazon rainforest

TEA [102]

There are inhabited areas INSIDE the Amazon Rainforest. Many primitive tribes with little to no contact of the outside world live in remote areas of the rainforest, but the closest major city to the rainforest (also inside) is Manaus, Brazil.
