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...

fibonacci(n_term) Output Our program first defines the first nth value (n1=0), then it checks if the n_term passed as an argument is equal to 1. If TRUE, it returns 0. Else, it defines two variables: count=0: This will be used in thewhile loopto check the condition if the coun...
