Question

Assume an array is defined as int[] nums = {7, 15, 23, 5};. Which of the following would place the values in the array in descending numeric order?

a. Array.Reverse(nums);

b. Array.Reverse(nums); Array.Sort(nums);

c. Array.Sort(nums);

d. Array.Sort(nums); Array.Reverse(nums);

Expert Solution

Step 1

Explanation:

Array.Reverse(nums) will reverse the order of elements in the array, but it will not sort them.
Array.Sort(nums) will sort the elements of the array in ascending order.
To sort the array in descending order, we first need to sort it in ascending order using Array.Sort(nums), and then reverse the order of elements using Array.Reverse(nums).
