Sample Script
// : Given
Integer[] array = new Integer[]{1,1,1,23,23,56,57,58};
DuplicateDeleter<Integer> deleter = new IntegerDuplicateDeleter(array);
// : When
Integer[] actual = deleter.removeDuplicateExactly(3);
// : Then
System.out.println(Arrays.toString(actual));
Sample Output
[23,23,56,57,58]
