A cashier distributes change using the maximum number of five-dollar bills, followed by one-dollar bills. Write a single stateme

Allushta [10]

Answer:

num_ones = amount_to_change % 5

Explanation:

It is given that the cashier has to change the money in the maximum number of 5 dollar bills and remaining as $1 bills.

We have to write a single statement of code to assign the value to variable num_ones to find the value of $1 bills given amount_to_change.

Let us solve this by taking example:

If amount_to_change = $19

Then total number of $5 bills that can be given is 3. And amount that can be given as $5 bills is $\bold{3 \times 5 = \$15}$

So, the remaining amount i.e. $19 - $15 = $4 will be given as one dollar bills.

Out of these $19, 4 bills of $1 can be found using the Modulus (%) operator.

Modulus operator leaves the remainder i.e.

Output of p % q is the remainder when a number 'p' is divided by 'q'.

19 % 5 = 4

4 is the number of one dollar bills to be given.

So, single line of code for the number of one dollar bills can be written as:

num_ones = amount_to_change % 5

Let us try it for amount_to_change = $30

We know that 6 number of $5 bills can be used to change the amount of $30 and no one dollar bill required.

num_ones = 30 % 5 = 0 (because 30 is completely divisible by 5 so remainder is 0)

So, the correct statement is:

num_ones = amount_to_change % 5

Write a recursive method that tests whether a string is a palindrome. It should return a boolean T or F depending on whether or

Sveta_85 [38]

Answer:

// program in java.

// library

import java.util.*;

// class definition

class Main

{

// recursive function to check palindrome

public static boolean isPalin(String str){

// base case

if(str.length() == 0 ||str.length()==1){

return true;

}

// if first character is equal to last

if(str.charAt(0) == str.charAt(str.length()-1))

{

// recursive call

return isPalin(str.substring(1, str.length()-1));

}

// return

return false;

}

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

try{

// object to read input

Scanner scr=new Scanner(System.in);

System.out.print("Enter a string:");

// read string from user

String myString =scr.nextLine();

// call function to check palindrome

if (isPalin(myString)){

System.out.println("Given String is a palindrome");

}

// if string is not palindrome

else{

System.out.println("Given String is not a palindrome");

}

}catch(Exception ex){

return;}

}

Explanation:

Read a string from user and assign it to variable "myString" with scanner object. Call the method isPalindrome() with string input parameter.In this method, if length of string is 0 or 1 then it will return true(base case) otherwise it will call itself and compare first character with last character.If string is palindrome then function will return true else return false.

Output:

Enter a string:ababa

Given String is a palindrome

Write a program to create an interface Shape containing the method declarations of area and perimeter. Then, create a class Rect

irakobra [83]

Answer:

Explanation:

An interface is similar to a class, to create an interface we use interface keyword, in an interface there can be abstract methods and constants only,we can not instantiate an interface.All the variables declared inside an interface are public,static and final by default.

While using interface child class must use implements keyword

We can define an interface by using below syntax-

<interface> <interface-name>{

}

For example lets create Shpae interface

interface Shape{

public int area(int length, int width);

public int perimeter(int length, int width);

}

Now lets create Rectangle class-

class Rectangle implements Shape{

public int area(int length, int width){

int area = 0;

area = length * width;

return area;

}

public int perimeter(int length, int width);

int perimeter = 0;

perimeter = 2*(length+width);

return perimeter ;

}
