Q$\mathrm{.}8)$ Consider an instance of TCP$\text{'}$s Additive Increase Multiplicative Decrease $($AIMD$)$ algorithmwhere the window size at the start of the slow start phase is $1$ MSS and the threshold at the startof the first transmission is $8$ MSS$.$ Assume that a timeout occurs during the $8$th transmission.Find the congestion window size at thend of the $20$th transmission.
