假设我们有一个数n。我们需要找到前n个斐波那契数的和(斐波那契数列前n项)。如果答案太大,则返回结果模10^8 + 7。 所以,如果输入为n = 8,则输出将是33,因为前几个斐波那契数是0 + 1 + 1 + 2 + 3 + 5 + 8 + 13 = 33 为了解决此问题,我们将遵循以下步骤 – m := 10^8+7 memo :=一个新...

Python入门之走向编程第一步一个例子开始 Of course, we can use Python for more complicated tasks than adding two and two together. For instance, we can write an initial sub-sequence of the Fibonacci series as follows当然，我们可以使用Python来完成比把两个和两个加在一起更复杂的任务。例如，我们...
