Question: Write a program named AlternatingSum.java that computes the alternating sum of all elements in an array. For example, if the user inputs the following values

Write a program named AlternatingSum.java that computes the alternating sum of all elements in an array. For example, if the user inputs the following values to be summed:

1 4 9 16 9 7 4 9 11

then it computes

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

The flow of the program must include the following steps:

1. Prompt the user for the number of values to be summed (n)

2. Prompt the user to enter in integers. A loop should be used to store the integers in an array.

3. Calculate and display the alternating sum.

Here is a sample run of the program:

the numbers must be read into an array before the alternating sum is calculated.
