In this problem, you need to simulate the actions taken by the logging and recovery manager discussed in the class. Consider the following log records and buffer actions:

time	LSN	Log	Buffer Actions
0	00	update: T1 updates P7	P7 brought in to the buffer
1	10	update: T1 updates P8	P8 brought into the buffer
2	20	begin_checkpoint
3	30	end_checkpoint
4	40	update: T2 updates P7
5		CRASH RESTART

For the actions listed above, show Transaction Table (XT) and Dirty Page Table (DPT) after each action. Assume that DPT holds pageID and recLSN, and XT contains transID and lastLSN.
