Write a recursive function that calculates if two binary trees are similar?

ahrayia [7]

Answer:

bool identicaltrees(Node* root1,Node* root2)//function of type boolean true if idenctical false if not.

{

if(root1==NULL&&root2==NULL)//both trees are null means identical.

return true;

if(roo1 && root2)

{

if(root1->data==root2->data)//condition for recursive call..

{

return (identicaltrees(root1->left,root2->right)&&identicaltrees(root1->right&&root2->right);

}

else

return false;

}

Explanation:

In this function it of type boolean returns true if both the trees are identical return false if not.First we are checking root node of both the trees if both are null then they are identical returning true.

If both root nodes are not null then checking their data.If data is same then recursively traversing on both trees and checking both trees.

else returning false.

a user reports that his dot matrix printer is printing dark and clear on the left of the paper but that the print is very light

yarga [219]

Answer:

Correctly position the platen of the printer to hold the paper in place.

Explanation:

Since the dot matrix printer is printing dark and clear on the left of the paper but very light on the right side of the paper, it is possible that the paper is not being held properly. So adjusting the platen will hold the paper properly and hence uniform prints on the paper.

Note: Dot matrix printers are printers that print closely related dots to form require texts (shapes) by striking some pins against an ink ribbon.

Some of the parts of these printers are; power supply, carriage assembly, Paper sensor, ribbon, platen and pins.

There are 12 inches in a foot and 3 feet in a yard. Create a class named InchConversion. Its main() method accepts a value in in

Dafna1 [17]

Answer:

import java.util.Scanner;

public class InchConversion

{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("Enter inches: ");

double inches = input.nextDouble();

inchesToFeet(inches);

inchesToYards(inches);

}

public static void inchesToFeet(double inches){

double feet = inches / 12;

System.out.println(inches + " inches = " + feet + " feet");

}

public static void inchesToYards(double inches){

double yards = inches / 36;

System.out.println(inches + " inches = " + yards + " yards");

}

Explanation:

In the inchesToFeet() method that takes one parameter, inches:

Convert the inches to feet using the conversion rate, divide inches by 12

Print the feet

In the inchesToYards() method that takes one parameter, inches:

Convert the inches to yards using the conversion rate, divide inches by 36

Print the yards

In the main:

Ask the user to enter the inches

Call the inchesToFeet() and inchesToYards() methods passing the inches as parameter for each method
