This second edition expands upon the solid, practical foundation established in the first edition of the text. A new four-part organizational structure increases the flexibility of the text, and all material is presented in a straightforward manner accompanied by an array of examples and visual diagrams.

First, there is no loop. The recursive version consists of a simple selection statement that returns either the value 1 or the

recursion. For example, in Chapter 6 we will study trees. Trees are a naturally recursive structure and recursion works well with them. In other cases the algorithm is naturally suited to recursion. For example, the binary search algorithm (see Chapter 13) lends itself to a natural recursive algorithm, as does the Towers of Hanoi algorithm, which we discuss later in this chapter. On the other hand, not all looping algorithms can or should be implemented with recursion, as we discuss below.

note that the bulk of the code in the algorithm is the mainline code to read the number of numbers to be generated and to print the results. There are actually only three statements in the recursive algorithm.

ensure that there is at least one item in the stack. If there is not at least one item, the stack is in an underflow state. ❏ The stack top operation only retrieves the item at the top of the stack. Each top execution must ensure that there is at least one item in the stack. If there is not at least one item, the stack is in an underflow state. ❏ Empty stack determines whether the stack is empty and returns a Boolean true if it is. ❏ Full stack determines whether there is room for at least

tell if the server is free?” The customer status record holds the answer. It represents either the current customer or, if there is no current customer, the previous customer. If there is a current customer, we cannot start a new customer. We can tell if the record represents the new customer by comparing the clock time with the end time for the customer. The end time is the start time plus the required service time. If the clock time is greater than the calculated end time, then, if the queue is
