Question: Write a static method called delete Repeat s that has a partially filled array of characters as a formal parameter and that deletes all repeated letters from the array. Because a partially filled array requires two arguments, the method should actually have two formal parameters: an array parameter and a formal parameter of type int that gives the number of array positions used. When a letter is deleted, the remaining letters are moved one position to fill in the gap. This creates empty positions at the end of the array so that less of the array is used. Because the formal parameter is a partially filled array, a second formal parameter of type int should tell how many array positions are filled. This second formal parameter cannot be changed by a Java method, so have the method return the new value for this parameter. For example, consider the following code:

1016_14.png

After this code is executed, the value of a[0] is a; , the value of a[1] is b; , the value of a[2] is c; , and the value of size is 3. (The value of a [3] is no longer of any concern, because the partially filled array no longer uses this indexed variable.) You may assume that the partially filled array contains only lowercase letters. Write a suitable test program for your method.
