Example-4.4 account A holds $1000. Assume the two operations are implemented by two threads, and assume that Consider a deposit of $100 and a withdrawal of $50 from account A. Initially, each instruction is atomic. Thread1: Thread2: t1 = A; t2 = A; t1 t1+$1003; t2 = t2 - 50; A = t1; A = t2; (a) What are the possible outcomes of the above transfer? For each outcome give a possible execution of the threads leading to that outcome. (b) Assume Thread1 repeats the deposit operation 3 times and Thread2 executes the withdraw operation 2 times (i.e., there are three depostis of $100 each, and 2 withdrawals of $5U each). What are the potential outcome?
