Question: Write a program that reads 10 integers then displays them in the reverse of the order in which they were read.
Example:
Enter array size
5
Enter element 1:
2
Enter element 2:
1
Enter element 3:
5
Enter element 4:
6
Enter element 5:
7
Output: 7 6 5 1 2

Step 1: Ask user to enter array size
Step 2: Create array with size user has entered
Step 3: Create a method which asks the user for array values
Step 4: Create method that displays the array
Step 4.1: Start the loop for length-1 till 0
