tekilochka [14]

Answer:

The following are the program to the given question:

import java.util.*;//import package for user input

public class Make  //define class Make

{

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

{

  Scanner obx = new Scanner(System.in);   //declare the Scanner class object

  int size=obx.nextInt(); //get the size of the array from the user

  int a[]=new int[size]; //declare an integer array with given size

  String word[]=new String[size]; //declare a string array with given size

  for(int i=0;i<size;i++) //set the for loop  

  word[i]=obx.next(); //get string input from the user

  for(int i=0;i<size;i++)   //iterates with the array, increase the count

  {

    for(int j=0;j<size;j++)   //defining a loop to check value

    {

      if(word[i].equals(word[j]))  //use if to check that elements of words          

      a[i]++;//increamenting array size

    }

  }

 System.out.print("\n");  //use print for break line  

  for(int i=0;i<size;i++)//set for loop to print the following result

    System.out.println(word[i]+" "+a[i]);//print value

 }

}

Output:

Please find the attachment file.

Explanation:

  • First, establish the predefined package required and instead define the main class and define the main method within the class and method.
  • Declare the scanner class object and receive an object size in the 'size' variable thru the array.
  • Next create two arrays, the integer type "a" with both the input size given and the string type "word" with the input size supplied.
  • Define the loop for which string array elements are acquired and set two to again for loop, which increases with loop iteration the integer data type array by one.
  • Lastly, set the loop for which this result is printed.

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.
