Integer numInput is read from input. Write a while loop that iterates until numInput is negative. At each iteration:

Update integer outputVal as follows:

If numInput is not divisible by 4, subtract numInput from outputVal.

Otherwise, add numInput to outputVal.

Then, read an integer from input into variable numInput.

Ex: If the input is 9 4 12 -3, then the output is:

Output value is 7

Note: x % 4 == 0 returns true if x is divisible by 4.
