Pand Q are two processes that share a set of variables that is common. The variable includes: seq, tA and tB: Before either process starts to execute, variable seg initially has the value 10. State the possible sets of different values of seg when both processes have finished executing. Provide an order of execution of statements from processes P and Q tha would produce each of the values you give. Justify your answer in detail.
