A run is a sequence of adjacent repeated values. Write a program that generates a sequence of 50 random die tosses in
an array and prints the die values, making the runs by including
them in parentheses, like this:

1 2 (5 5) 3 1 2 4 3 (2 2 2 2) 3 6 (5 5) 6 3 1

Add a method alternatingSum() that returns the sum of the
alternating elements in the array and subtracts the others. For
example, if your array contains:

1 4 9 16 9 7 4 9 11
Then the method should compute:

1-4+9-16+9-7+4-9+11 = -2

I am having trouble with this code can someone please help me?
