Consider transactions T1, T2, T3 with timestamps 10, 20, and 30, respectively in a database system that follows multi-version concurrency control protocol. T1 is a reader and T2 and T3 are writer transactions.

Let T1 read and T2 read and update data item D. If transaction T3 updates only D, provide a schedule where the multi-version concurrency control method will not restart T3.

Please explain why the schedule is correct.
