Given the following transactions TI. T2, and T3 TI Read(A) Read(C) Read(B) Read(B)Write(C) Write(B) Write(A) Read(A Read(C) Write(B)Write(A)te(C) Read(D) Write(D) Write(D) T2 T3 Note that the above is NOT a schedule- it just shows 3 transactions. (a). Add locking and unlocking statements to TI, T2 and T3, according to the two-phase locking protocol, and show the resulting transactions (with locking/unlocking state- ments) TI'. T2' and T3 b). Show a concurrent (non-serial) schedule S for TI'. T2', and T3' such that S is dead-lock free. Draw the Wait-for graphs for S (c). Show a partial concurrent (non-serial) schedule S' for TI'. T2', and T3' such that S' is dead-locked. Draw the wait-for graphs for S
