There exist two servers S$1$ and S$2.$ Both servers support the following services:

Services supported by server S$1$:

int SetPrice$($string$,$ float$)$

float GetPrice$($string$)$

void BuyStock$($string$,$ int$)$

void SellStock$($string$,$ int$)$

Services supported by server S$2$:

int SetPrice$($string$,$ int$)$

float GetPrice$($string$)$

void BuyStock$($int$,$ string$)$

void SellStock$($string$,$ int$)$

int SetPrice$($string$,$ float$)$

There exist two servers S$1$ and S$2.$ Both servers support the following services:

Services supported by server S$1$: int SetPrice$($string$,$ float$)$

float GetPrice$($string$)$

void BuyStock$($string$,$ int$)$

void SellStock$($string$,$ int$)$

Services supported by server S$2$: int SetPrice$($string$,$ int$)$

float GetPrice$($string$)$

void BuyStock$($int$,$ string$)$

void SellStock$($string$,$ int$)$ int SetPrice$($string$,$ float$)$

There exist two client processes and they request the following services:

Client$-$A

int SetPrice$($string$,$ float$)$ float GetPrice$($string$)$ void BuyStock$($int$,$ string$)$ void SellStock$($string$,$ int$)$

Client$-$B

int SetPrice$($string$,$ int$)$ float GetPrice$($string$)$ void BuyStock$($string$,$ int$)$ void SellStock$($string$,$ int$)$

The client processes do not know the location $($pointer$)$ of servers that may provide these services. Devise a software architecture using a Client$-$Broker$-$Server architecture for this problem. In this design, the client processes are not aware of the location of the servers providing these services.

$$ Provide a class diagram for the proposed architecture. In your design, all components should be decoupled as much as possible.

$$ Provide the pseudocode for all operations of the following components$/$classes: o Broker

o Client Proxy of Client$-$A

o Server Proxy of server S$1.$

$$ Provide a sequence diagram to show how Client$-$A gets $$int SetPrice$($string$,$ float$$ service.
