Our implementation of insert for the DynamicArray class, as given in Code Fragment above has the following inefficiency. In the case when a resize occurs, the resize operation takes time to copy all the elements from an old array to a new array, and then the subsequent loop in the body of insert shifts many of those elements. Give an improved implementation of the insert method, so that, in the case of a resize, the elements are shifted into their final position during that operation, thereby avoiding the subsequent shifting.
