Explain what would happen to the algorithms and the time complexity of an array implementation of the stack if the top of the stack were at position 0.
What will be an ideal response?
A array-based stack implementation can take advantage of the fact that all processing on the stack takes place on one end. By implementing it so that the bottom of the stack (the "inactive" end) is at position 0, elements are added and removed at higher index values. If the top of the stack were designed to be at position 0, then all activity would take place there, and the remaining elements of the stack would have to be shifted one position every time an element was pushed or popped, which would be inefficient.
