Fibonacci (Fibonacci) sequence

1. Find the first 40 numbers of the Fibonacci sequence. This sequence has a characteristic: the first and second numbers are 1 and 1. Starting with the third number, the number is the sum of the two preceding numbers. That is, the number sequence is 1, 1, 2, 3, 5, 8, 13....

5. Program Analysis
   The program outputs a total of 40 numbers. Although the program is correct and the running result is correct, the algorithm is not the best, and each number output occupies one line, which is too large and not advisable.
