Requests to access specific cylinders on a disk drive arrive in this order: 24, 20, 4, 40, 6, 38, and 12, and the seek arm is initially located at cylinder 20. If the average seek time is 6 milliseconds, what is the total seek time for the following algorithms:a. First-comeb. first served; c. Closest cylinder next; d. Elevator algorithm

When you reach a yield sign, yield to cross traffic and before you enter the intersection. a. flash your headlights b. wait for a signal c. wait five seconds d. wait for a safe gap

Write a modular program (no classes yet, just from what you learned last year), that allows two players to play a game of tic-tac-toe. use a two-dimensional char array with 3 rows and 3 columns as the game board. each element of the array should be initialized with an asterisk (*). the program should display the initial board configuration and then start a loop that does the following: allow player 1 to select a location on the board for an x by entering a row and column number. then redisplay the board with an x replacing the * in the chosen location. if there is no winner yet and the board is not yet full, allow player 2 to select a location on the board for an o by entering a row and column number. then redisplay the board with an o replacing the * in the chosen location. the loop should continue until a player has won or a tie has occurred, then display a message indicating who won, or reporting that a tie occurred. player 1 wins when there are three xs in a row, a column, or a diagonal on the game board. player 2 wins when there are three ox in a row, a column, or a diagonal on the game board. a tie occurs when all of the locations on the board are full, but there is no winner. input validation: only allow legal moves to be entered. the row must be 1, 2, or 3. the column must be 1, 2 3. the (row, column) position entered must currently be empty (i.e., still have an asterisk in it).

Elements such as fonts colors visual structure graphics and the interface of a web page should complement each other to ensure blank
