A group of four processes P0-P3 sends out multicasts in a run as shown below. The group is using causal ordering for multicasts. All sequence numbers start with zeros. Answer the following question. The sequence vector associated with the send event of the last (i.e., second) multicast that P1 sends out, as a comma-separated list (without the brackets), is: A group of four processes P0-P3 sends out multicasts in a run as shown below.
