Consider the figure below in which a TCP sender and receiver communicate over a connection in which the sender$->$receiver segments may be lost. The TCP sender sends an initial window of $5$ segments. Suppose the initial value of the sender$->$receiver sequence number is $229$ and the first $5$ segments each contain $422$ bytes. The delay between the sender and receiver is $7$ time units, and so the first segment arrives at the receiver at $t=8.$ As shown in the figure below, $3$ of the $5$ segment$($s$)$ are lost between the segment and receiver.

T$$n $..............$

Give the sequence numbers associated with each of the $5$ segments sent by the sender$.$ Format your answer as: a$,$b$,$c$,...$

Give the ACK numbers the receiver sends in response to each of the segments. If a segment never arrives use $\text{'}x\text{'}$ to denote it$,$ and format your answer as: $a,b,c,$dots
