CHALLENGE ACTIVITY
1.13.2: Outputting all combinations.
 
Output all combinations of character variables a, b, and c, in the order shown below. If a = 'x', b = 'y', and c = 'z', then the output is:
xyz xzy yxz yzx zxy zyxNote: If outputting multiple character variables with one statement, the argument for System.out.print() should start with "" +

Your code will be tested in three different programs, with a, b, c assigned with 'x', 'y', 'z', then with '#', '$', '%', then with '1', '2', '3'.

ACTIVITY
A common error is to use double quotes rather than single quotes around a character literal, as in myChar = "x", yielding a compiler error.
Similarly, a common error is to forget the quotes around a character literal, as in myChar = x, usually yielding a compiler error (unless x is
also a declared variable, then perhaps yielding a logic error).
