1.Method printReverse

Given an array of integers, and the number of elements in the array, print all the elements in the array in reverse order.

Consider the case when the array is empty and output the message, The array is empty.

2.Method overwriteOdds

Given an array of integers, and the number of elements in the array, overwrite all the odd numbers in the array with 0. Do NOT print the array; the testing section will print the array.

3.Method findIndexSmallest

Given an array of integers, and the number of elements in the array, find the index of the smallest element in the array and print it out on the screen.

Do NOT print the array; the testing section will print the array.

4.Method countMultiples

Given an array of integers, and the number of elements in the array, count all elements in the array that are multiples of 3, but do NOT count number 3 itself, and print out the total count.

Do NOT print the array; the testing section will print the array.

5.Method alternatedSum

Given an array of integers, and the number of elements in the array, sum up every other element in the array starting at index 0, and print out the result.

Do NOT print the array; the testing section will print the array.

6.Method copyArray

Given an array of integers, and the number of elements in the array, create a new array of integers with length equal to the length of the given array, and copy all the elements of the given array into the new array.

Use two for loops: The first will copy the array and the second will print it.

Consider the case when the given array is empty and output the message, The array to copy from is empty. Print out the new array.

7. Method copyEveryOther

Create a new array of integers with length equal to the length of the given array, and copy every other element of the given array into the new array, starting at index 0.

Use two for loops: The first will copy the array and the second will print it.

Consider the case when the given array is empty and output the message, The array to copy from is empty.
