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...

For the purposes of this example, you’ll use a somewhat silly function to create a piece of code that takes a long time to run on the CPU. This function computes the n-th Fibonacci number using the recursive approach: Python >>> def fib(n): ... return n if n < 2 else fib...
# Fibonacci numbers module def fib(n): # write Fibonacci series up to n a, b = 0, 1 while b < n: print(b, end=' ') a, b = b, a+b print() def fib2(n): # return Fibonacci series up to n result = [] a, b = 0, 1 while b < n: result.append(b) a, b = b,...
Write a Python program to get the Fibonacci series between 0 and 50. Note : The Fibonacci Sequence is the series of numbers : 0, 1, 1, 2, 3, 5, 8, 13, 21, ... Every next number is found by adding up the two numbers before it. Expected...
It’s quitecommon to divide our program into chunks using functions which we can call later to perform some useful action. 使用函数将程序分为多个块是很常见的,稍后我们可以调用这些函数来执行一些有用的操作。 Sometimes, a function can become expensive to call multiple times (say, a function to ...
