Question $3.(20$ pts$.)$ Suppose you are creating RPI Campus Paths application using the Model$-$View$-$Controller design

pattern to organize your code. As with all good software, you want to make some changes to it in the future.

For each of the following possible changes, select Model, View, and$/$or Controller to indicate which component$($s$)$ of the

application would need to be modified in order to implement that change.

You should answer the question based on a cleanly designed MVC organization for RPI Campus Paths, even if your own

code is somewhat different.

a$)$ Modify the shortest$-$path$-$finding algorithm $($Dijkstra$$s$)$ to use integer edge weights instead of doubles.

$$ Model

$$ View

$$ Controller

b$)$ Change the color of text in which a path is displayed to blue.

$$ Model

$$ View

$$ Controller

c$)$ Replace all uses of ArrayList in the graph implementation with LinkedList.

$$ Model

$$ View

$$ Controller

d$)$ Change the application so that building names are displayed in lower$-$case letters only.

$$ Model

$$ View

$$ Controller

e$)$ Translate the application$$s UI into French.

$$ Model

$$ View

$$ Controller

f$)$ Change the application so that it works with campus map for MIT instead of RPI.

$$ Model

$$ View

$$ Controller

g$)$ Change the application so that it now uses GUI instead of console text$-$based UI$.$

$$ Model

$$ View

$$ Controller

h$)$ Change the application so that the total length of the path is shown in miles$/$kilometers instead of pixel units.

$$ View
