Two agents (threads) sell tickets to a concert. Each thread will loop selling tickets until there are no more tickets left to sell. Clearly total number of tickets that can be sold (numtickets) is a global variable. Note: Write the pseudo code for one thread only. The other one should have the same code except the thread name so no need to repeat it. a. Write a pseudo code to guarantee that the total number of tickets sold do not exceed numtickets ( 15 points) b. When all tickets are sold, each thread prints the number of tickets sold by the thread ( 10 points)
