4. Create a class named HotelRoom that includes an integer field for the room number and a double field for the nightly rental rate. The constructor of this class requires an integer argument representing the room number and the constructor sets the room rate based on the room number; rooms numbered 299 and below are $69.95 per night, and others are $89.95 per night. Create an extended class named Suite whose constructor requires a room number and adds a $40 surcharge to the regular hotel room rate, which again is based on the room number. Write an application named UseHotelRoom that creates an object of each class, accept room number from user, demonstrate that all the methods work correctly and display the details. Save the files as UseHotelRoom.java.

Suppose a system has not implemented any deadlock prevention and avoidances measurement. Therefore, it has to run the deadlock detection algorithm in case deadlock has occurred in a system. Following two strategies can be adopted to recover the system from a deadlock.

1. Abort the one or more processes to break the circular wait.
2. Preempt some resources from one or more processes to break the deadlock.

In your opinion, which option will be considered more suitable to recover the system from a deadlock? Write a concise and to the point answer with valid reasons.

In this python program it has two test cases, in this two test cases one test case was getting expected output and second test case are not getting expected output. Please give me expexted output for two test cases. Thank you !

Hints:

• Use the end operator to print all the Armstrong numbers in a single line.
• If there is no Armstrong numbers between the given range A to B(including A and B) print -1

Product of the Given Numbers

Given an integer using WHILE LOOP

N, write a program which reads N inputs and prints the product of the given input integers.Input

The first line of input is a positive integer,

N. The next N lines each contain an integer.Output

The output should be the product of the given input integers.

Explanation

In the given example,

N = 3 and the input integers are 2, 3, and 7.So, the output should be 2 x 3 x 7 = 42

N as a starting number and K as input, write a program to print a number pyramid of K rows as shown below.Input

The first line of input is an integer

N. The second line of input is an integer K.Explanation

In the example, the given starting number is

10, and the number of rows in the pyramid is 5.So, the output should be

10

11 12

13 14 15

16 17 18 19
