Part IV: 1. Consider a deposit of $100 and a withdrawal of $50 from account A. Initially, account A holds $1000. Assume the two operations are implemented by two threads, and assume that each instruction is atomic. Thread 1: Thread2: t1 =A; t2 = A; t1 = t1 = 100; t2 = 12 - 50; A=1; A= 12; What are the possible outcomes of the above transfer? For each outcome give a possible execution of the threads leading to that outcome.[10points od sonsonbon
