Answer:</h2>
Authorization specifies what a user can do, and access control enforces what a user can do.
<h2>
Explanation:</h2>
Authorization is simply granting access to an authenticated user of an application. It specifies what a user can and/or cannot do. For example, for a user to access their banking details in an online banking service, they have to be authorized by first authenticating them to prove their identity. Another example is in an organizational system where some users (normally called admins) can access certain database info whereas some other users (normally called the regular users) cannot.
Access control is used to enforce the policies dictated by authorization. In other words, access control enforces the policy of what a user can and/or cannot do. Access control makes authorization possible. It is sometimes called privileges or permissions. For example, the <em>security tab </em>in the operating system of Windows, allow to set access privileges for certain files and/or folders. Another example is in an organizational system where some files on the organization's server are configured in such a way that access to it is restricted and dependent on some further authorization.

Answer:
In recursive methods, if a temporary variable is used to store intermediate results, then number of copies it will make is equal to recursive calls made during recursions
Explanation:
If a temporary variable is used to store intermediate result than it make a new copy every time when the recursive method calls itself until the last recursive call. So for that recursive methods are not storage efficient because they push and pop results of each call on memory.
