data structures

The goal of this assignment is to implement a dynamic array for some of the data structures we covered in this course. The size of the array that holds the data structure is static. Thus, when the data structure is full and the user tries to add a new element, an error occurs. Your goal is to 'grow' the array when some space is needed. When inserting a new element and the array is full, we do the following: 1- Allocate a new array temp with a capacity that is twice as large as the original array (for example A). 2- Copy all the elements from the original array to the new array, temp. When copying the elements, you must make sure that the structure is correct. For example, when you copy the heap, the maximum element will stay as the maximum element. For Queue, the front element will not be changed. The index of the front element might need to be changed. For Hash, you must the elements when you copy them to the temp array. 3- Make the original array variable points to the new array temp (e.g., A=temp). You must implement the expand method in the four classes, ArrayStack, ArrayQueue, HeapPriorityQueue, and LinearProbingHashTable. The expand method is already added to the class and some code is provided. You should complete the implementation. Make sure the testing code provided in Testingassignment2. java is working correctly. You should uncomment the code that tests the addition of the extra elements in each testing method: testingStack(), testingQueue(), testingHeapPriorityqueue()
