Problem LeetCode TheFibonacci numbers, commonly denotedF(n)form a sequence, called theFibonacci sequence, such that each number is the sum of the two preceding ones, starting from0and1. That is, F(0)=0,F(1)=1F(N)=F(N-1)+F(N-2),forN>1. GivenN, calculateF(N). Example 1: Inp...

To calculate the tenth Fibonacci number, you should only need to calculate the preceding Fibonacci numbers, but this implementation somehow needs a whopping 177 calculations. It gets worse quickly: 21,891 calculations are needed for fibonacci(20) and almost 2.7 million calculations for the thirtieth...
"""Calculate the sum of all given numbers.""" return sum(args) print(sum_numbers(1, 2, 3, 4)) 在这个示例中,*args允许函数接收任意数量的参数,并在函数体中将其视为一个元组。 三、返回值 函数的返回值是函数的输出结果。return语句用于将结果返回给调用者。如果没有指定返回值,函数默认返回None。
