X1145: Map Union
A teacher is tracking grades for two sections of a class using two
maps.
Each map uses the student's name as a key with their grade is the corresponding value, stored as a Double.
So far, the teacher has been keeping the two sections of the class in two seperate maps. However, now the teacher wants to combine both sections into one map.
Below, you see a class with two Map fields
representing the two sections of the class. Implement the
method mapUnion() so that it creates a new map that
contains all the key/value pairs from both sections and
then returns that new map.
You can use either a HashMap or TreeMap here.
You can assume that all name keys in both sections are unique.
