$3\mathrm{.}4-3$ The RDT $2\mathrm{.}2$ protocol $($c$).$ Consider the rdt $2\mathrm{.}2$ sender and receiver below, with FSM transitions labeled in red. Also consider the sender and receiver timeline following the FSMs$,$ where a green OK label indicates a message that is not corrupted, and a red corrupt label lindicates a message that is comupted. We are interested in the sequence number $(0$ or $1)$ of a data message, and the ACK number $(0$ or $1)$ of an ACK message for the messages sent at $t=2,3,4,5$ in the figure below.

For the messages sent at $t=2($data sequence number$)$; $t=3($ACK number$),t=4($data sequence number$),$ and $t=5($ACK number$),$ what are the equence$/$ACK numbers ascociated with each message? Only one sequence is correct.

As an example, $1,0,1,0$ means the data sent at $t=2$ has seq number $1,$ and the ACK sent at $t=3$ has ACK number $0,$ the data sent at $t=4$ has seq number $1,$ and the ACK sent at $t=5$ has ACK number $0.$
