Finding number of Conflict Serializable schedule..

They are taking 2 Transactions..

        T1:R1(A)  W1(A) R2(B)  W2(B)

        T2:R2(A)  W2(A)  R2(B) W2(B)

How it is possible to take a operation with suffix 2 in Transaction 1..?

That video is confusing sir..

Could you please explain that clear...

Thanks in advance-:)

Thanks a mistake, thanks for informing.

In transaction T1 all the subscripts should be "1". So, it is:
T1: R1(A) W1(A) R1(B) W1(B)
