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.

when you select cells in your worksheet and then click the copy button, what happens? select one: a. the formatting is removed f

Amiraneli [1.4K]

Hey there! Hello!

Not sure if you still need this answer, but I'd love to help out if you do.

In terms if Excel Spreadsheet, your answer will be D. A<span> moving dashed line border appears around the cells. What the copy button does is take the contents in your cell(s) and copies them so that you can paste them elsewhere. B and C would apply here if you were cutting the text, which clears whatever you have selected so that you can paste them elsewhere without having to go back and delete it.

I have attached an example of what happens to a cell when you either right click it and press copy, or press ctrl/command+c, which is the keyboard shortcut for copying text or contents.

Hope this helped you out! Feel free to ask me any additional questions if you have any. :-)</span>

. The variable numbers is a 2-dimensional array of type int; output all of its elements that are strictly greater than 10

lana66690 [7]

Answer:

// here is code in c++.

#include <bits/stdc++.h>

using namespace std;

int main()

{

// variable to read row and column of 2-d array

int r,c;

cout<<"enter the number of row:";

// read number of row

cin>>r;

cout<<"enter the number of column:";

// read number of column

cin>>c;

// create an array of size rxc

int arr[r][c];

cout<<"enter the elements of the array:"<<endl;

// read the elements of 2-d array

for(int i=0;i<r;i++)

{

for(int j=0;j<c;j++)

{

cin>>arr[i][j];

}

cout<<"numbers which are greater than 10 in 2-d array"<<endl;

for(int i=0;i<r;i++)

{

for(int j=0;j<c;j++)

{

// if element is greater than 10, print it

if(arr[i][j]>10)

cout<<arr[i][j]<<" ";

}

cout<<endl;

}

return 0;

}

Explanation:

Read the size of 2-d array i.e row and column.Create a 2-d array of size rxc of integer type.Read the elements of the array. Then traverse the array and if an element if greater than 10 then print that element.

Output:

enter the number of row:3

enter the number of column:3

enter the elements of the array:

23 45 53 78 1 9 6 8 77

numbers which are greater than 10 in 2-d array

23 45 53

78
