practical question: one month as the trial period, each person sold 100 wonderful smart combs. Anyone who passes this question can prove that he is an effective person and can immediately become a formal employee of the wonderful company, enjoy 'salary of RMB + performance bonus." The students were shocked and talked about: "How many combs can be sold in one month? Wrong? How is this possible ?" Dong Zhuo made everyone quiet and further explained: "the reason for this practical question is that

series of function calls and a series of repeated computations may occur, the execution efficiency of recursive algorithms is relatively low. When a recursive algorithm can be easily converted into a recursive algorithm, programs are usually compiled based on the recursive algorithm. For example, for the above example, the function fib (n) of the nth item of the Fibonacci series should adopt a recursive algorithm, that is, the next item is calculated from the first two items of the Fibonacci se
