Question

The add method for a dynamic array, as described in Code Fragment 7.5, has the following inefficiency. In the case when a resize occurs, the resize operation takes time to copy all the elements from the old array to a new array, and then the subsequent loop in the body of add shifts some of them to make room for a new element. Give an improved implementation of the add method, so that, in the case of a resize, the elements are copied into their final place in the new array (that is, no shifting is done).
