What are the disadvantages of Peterson’s solution for critical-section problem? Code below shows the solution to two process mutual exclusion problem. Process Pi
do {
flag[i] = true;
turn = j;
while (flag[j] && turn == j);
critical section
flag[i] = false;
remainder section
} while (true);
Process Pj
do {
flag[j] = true;
turn = i;
while (flag[i] && turn == i);
critical section
flag[j] = false;
remainder section
} while (true);

Answer True or False to the following questions:

a. This algorithm satisfies the "mutual exclusion", "progress" and "bounded waiting" condition.
b. This algorithm has a flaw as the variable "turn" can be modified by both processes at the same time.
c. This algorithm may cause "deadlock" if both processes set their flags to True at the same time.
d. This algorithm satisfies only the "mutual exclusion" and "progress" condition

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).
