Question

Consider the following two transactions: T1: read(A) read(B); If A=0 then B:=B+1; write(B). T2: read(B); write(A); If B=0 then A :=A+ 1; write(A). Add lock and unlock instructions to transactions T1 and T2, so that they observe the two.-phase locking protocol. Can the execution of these transactions result in A deadlock?​
