Suppose a program contains a recursive method findFibonacci(int n), which computes the n-th Fibonacci number. Even if we know that a client method will never call findFibonacci( ) with the values 1 or 2 as arguments, why does the implementation of findFibonacci( ) still need to have base cases?
What will be an ideal response?
In the course of findFibonacci’s own recursion it will eventually reach values of n = 1 or 2 that it passes to itself. If these are not identified as base cases, then the recursion will logically continue forever, which is incorrect.

What is the best way to fix a table with repeating groups?
A) Create additional columns for repeating data. B) Export table to Excel, fix repeating groups, then import back to Access.

Answer the following statements true (T) or false (F)
1. The two most common queue operations are push and pop. 2. When the program knows the exact contents of a list and can access any element on demand, the data structure is known as a stacked deque. 3. For a compiler that is older than C++11 it is necessary to put spaces between the angled brackets that appear next to each other when defining a stack. 4. Computer systems use stacks. For example, when a function is called, they create local variables on a stack which are removed from the stack when the function terminates.
