Drive’s License Exam

The local driver’s license office has asked you to design a program that grades the written portion of the driver's license exam. The exam has 20 multiple choice questions. Here are the correct answers:

  1. (1) B
  2. (2) D
  3. (3) A
  4. (4) A
  5. (5) C
  6. (6) A
  7. (7) B
  8. (8) A
  9. (9) C
  10. (10) D
  11. (11) B
  12. (12) C
  13. (13) D
  14. (14) A
  15. (15) D
  16. (16) C
  17. (17) C
  18. (18) B
  19. (19) D
  20. (20) A

Your program should store these correct answers in an array. (Store each question's correct answer in an element of a String array.) The program should ask the user to enter the student's answers for each of the 20 questions, which should be stored in another array. After the student's answers have been entered, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam.) It should then display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly answered questions.

a) first player is the minimizing player. What move should be chosen?b) What nodes would not need to be examined using the alpha-beta pruning procedure?
Consider the problem of finding a path in the grid shown below from the position S to theposition G. The agent can move on the grid horizontally and vertically, one square at atime (each step has a cost of one). No step may be made into a forbidden crossed area. Inthe case of ties, break it using up, left, right, and down.(a) Draw the search tree in a greedy search. Manhattan distance should be used as theheuristic function. That is, h(n) for any node n is the Manhattan distance from nto G. The Manhattan distance between two points is the distance in the x-directionplus the distance in the y-direction. It corresponds to the distance traveled along citystreets arranged in a grid. For example, the Manhattan distance between G and S is4. What is the path that is found by the greedy search?(b) Draw the search tree in an A∗search. Manhattan distance should be used as the
