Explain the concept of interface segregation principle (ISP) in the context of software design. Why is it important, and how can it be applied?
My student claimed that the three fundamental page replacement algorithms (FIFO, LRU, and optimal) are identical in their abstract design, with the exception of the characteristic that is used to choose the page to be replaced. I was of the opposite opinion.(a) What is the property of the FIFO algorithm that you are referring to? (b) What is the name of the algorithm that you are referring to? What is the LRU algorithm and how does it work? What is the pptimal algorithm in its most basic form?The general algorithm for these page replacement strategies should be included in the specification (b).
Code requirements: A robot is positioned on an integral point in a two-dimensional coordinate grid (xr, yr). There is a treasure that has been placed at a point in the same grid at (xt, yt). All x’s and y’s will be integral values. The robot can move up (North), down (South), left (West), or right (East). Commands can be given to the robot to move one position in one of the four direction. That is, “E” moves a robot one slot East (to the right) so if the robot was on position (3, 4), it would now be on (4, 4). The command N would move the robot one position north so a robot at position (4, 4) would be at (4, 5). Because the robot cannot move diagonally, the shortest distance between a robot at (xr, yr) and a treasure at (xt, yt) is | xr – xt | + | yr - yt | = ShortestPossibleDistance Write a recursive program which determines all the unique shortest possible paths from the robot to the treasure with the following stipulation: The robot may never move in the same direction more than…
Given the following UML diagram: Student - studentID: String + getStudentID(): String + toString(): String Person - lastName: String - firstName: String - dateOfBirth: Date - address: Address + getName(): String + getDOB(): Date + getAddress(): Address + toString(): String Professor - employeeID: String + getEmployeID(): String + toString(): String Write an implementation for the class Professor. DO NOT include or implement any constructor for this class. There are no abstract methods/classes in this example. toString method will return any simple String that contains firstName and employeelD only; no less, no more!! Assume firstName was defined as protected in class Person. You are not allowed to add implementation for any class or methods other than what is listed in the question statement. 2
According to my student, the abstract design of the three basic page replacement algorithms (first-in, first-out (FIFO), and last-in, last-out (LRU), and optimum) is similar, with the only difference being the characteristic that is utilized to determine the page to be replaced. Personally, I thought the exact opposite.(a) When you say that the FIFO algorithm has this quality, what exactly do you mean? What is the name of the algorithm you're referring to in (b)? Just what is the LRU algorithm, and how does it function? In its simplest form, what is the pptimal algorithm?It is recommended that the specification contain the general method for these page replacement schemes (b).
