Concurrency Consider the following processes P1 and P2 that update the value of the shared variables, $x$ and $y$, as follows: Process P1: ( performs the operations: $\mathrm{x}:=\mathrm{x}?\mathrm{y}$ $\mathrm{y}++$ ) LOAD R1, $\mathrm{X}//(A)$ LOAD R2, Y // (B) MUL R1, R2 // (C) STORE X, R1 // (D) INC R2 // (E) STORE Y, R2 // (F) Process P2 : ( performs the operations: $\mathrm{x}++$ $\mathrm{y}:=\mathrm{x}?\mathrm{y}$ ) LOAD R3, X //(G) INC R3 //(H) LOAD R4, Y // (I) MUL R4, R3 // (J) STORE $X$, R3 // (K) STORE Y, R4 //(L) Assume that the initial values of $x$ and $y$ are 2 and 3 , respectively. Question 1 P1 and P2 execute serially (one after the other without any interleaving or concurrent execution). What would the values of $x$ and $y$ be after the execution? Answers are separated by a comma, no space. E.g: 2,3 Question 2 $\mathrm{P}1$ and $\mathrm{P}2$ are interleaved and the trace of their execution is the following: $(\mathrm{A})?(\mathrm{B})?(\mathrm{G})?(\mathrm{H})?(\mathrm{I})?(\mathrm{C})?(\mathrm{D})?(\mathrm{E})?(\mathrm{F})?(\mathrm{J})?>(\mathrm{K})?(\mathrm{L})$ What would the values of $x$ and $y$ be after the execution of all instructions? Answers are separated by a comma, no space. E.g: 2,3
