Software Engineering please answer $1-$ Find and correct the mistakes in the following diagrams. Show your corrections on the diagrams $(10$ points$)$

$2-$ Read the system description for the Aegis combat system and draw the corresponding component diagram $(20$ points$)$

The Aegis combat system consists of a set of components interacting with each other. The Experiment Control at the top of the diagram provides information, obtained via sensors$,$ to its connected components. The Track Server requires the track information from the Experiment Control, for determining the location of the enemies that operate around the ship. The Track Server shen provides the location information to its own connected components. The Doctrine Authoring requires doctrine rules from the Es$-$ periment Control and provides them to itx connected components, which require rules to take actions. Using the doctrine rules and track information from its environment, the Geo Server calculates region information for enemies and provides them to the Doctrine Reasoning Lanity, the Doctrine Reasoning makes the decision of which tank$($s$)$ to take against the enemies

$3.$ You are expected to read the following problems and propose a design pattern for solving them. Explain your proposal $(1\mathrm{.}5$ what makes you choose that particular design pattern among many of those$).(10$ points$)$

$3\mathrm{.}1-$ The auction $($m$$zayede$)$ is started by the auctioneer, informing all the participants. Then, the auctioneer calls the bidders $($tek lif verenler$)$ for their participation to the auction. Each bidder makes a bid $($teklif$)$ for the good, which is either $(1)$ accepted if proposed price is greater than the current price of the good or $($ii$)$ rejected by the auctioneer if it is less. Once the bidder bid in cepted, the auctioneer updates the good's current price with the brace of the accepted bid. The auctioneer keeps calling the bidden for their participation until everyone rejects the updated price of the good, which indicates that the auction ends at that point.
