 The set functions can be used with cell arrays of strings. Create 

two cell arrays to store (as strings) course numbers taken by two 

students. For example,

s1 = {'EC 101', 'CH 100', 'MA 115'};

s2 = {'CH 100', 'MA 112', 'BI 101'};

Use a set function to determine which courses the students have in
