Question: Write a defining table and a function that returns the sum of the first and last values in an array. The function must have this

Write a defining table and a function that returns the sum of the first and last values in an array. The function must have this header:

function addEnds(list)

Hint: To test your two functions write a separate function that is called from the onclick attribute of a button. This separate test function should create one or more arrays, call the addEnds and getMiddle functions and display the values returned from addEnds and getMiddle.

Tips for Using the Auto-Grader

CIT 160 uses automatic grading technology to grade your programming assignments. Using this auto-grader allows you to receive instant feedback about your programs instead of waiting days or weeks to learn if your programs are correct or not. It also frees instructors from the heavy burden of grading many programs and allows them to spend more time helping students learn instead of grading their work. Of course, the auto-grader is not a human and is not as smart nor as flexible as a human in recognizing correct programs.
