Write a method that takes an integer array as its parameter and sorts the contents of the array in ascending order using the Insertion Sort algorithm. Call this method after the original array (original program below) and other stats have been displayed. Once the array has been sorted by your method, display its contents to the screen in the same manner as the original array was displayed.
Write a method that
takes an integer array as its parameter and sorts the contents of the array in
ascending order using the Insertion Sort

been sorted by your method, display its contents to the screen in the same
manner as the original array was displayed.
