The TSA (Transportation Security Administration) at a major airport is evaluating a new policy of screening its customers. Current Policy (Policy 1): The TSA is managing three independent queues with one sever responsible for each queue. The customers arrive at the system and immediately are divided equally likely to each of the independent queues. New Policy (Policy 2): The new policy that TSA is preparing to implement is - pool all the three servers and manage the waiting of customers with a single queue. You are hired as an Operations analyst to evaluate both policies. The TSA has provided you with the following data - The inter-arrival time between customers arriving to the system and service time for each customer by a server follows an exponential distribution with a mean of 5 and 12 minutes respectively.

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).
