Question

Assume that the array arr has been defined and initialized with the values {4, 2, 5, 3, 1}. What are the values in the array arr after the first pass of the while loop (i.e. when n is reduced to arr.length - 2 by the line before the point indicated by /* end of while loop */)

Answer 1

Answer:

arr = [4, 2, 5]

Explanation:

The while loop will remove the array elements from the back.
