This technical question is asking you to compare two concepts used in the role of a software engineer. When comparing two concepts, you should first define each of them and then discuss how they differ. It may be helpful if you provide examples of how the concepts are used and the work you do to demonstrate your understanding of the subject matter. These types of questions are typical when interviewing at SalesForce or any leading cloud-based software organization.

"A stack is a data structure that utilizes the last in, first out principle for presenting data to the application. On the other hand, an array doesn't have a fixed structure for how data is added or retrieved by the application. A stack may be used in an application that requires the most recent data to be presented first. An array can be used to retrieve any of the data, regardless of when it was added to the application."
