巨大的斐波那契数 The i'th Fibonacci number f (i) is recursively defined in the following way: f (0) = 0 and f (1) = 1 f (i+2) = f (i+1) + f (i) for every i ≥ 0 Your task is to compute some values of this sequence. Input begins with an integer t ≤ 10,000, th…
How many Fibs? Description Recall the definition of the Fibonacci numbers: f1 := 1 f2 := 2 fn := f n-1 + f n-2 (n>=3) Given two numbers a and b, calculate how many Fibonacci numbers are in the range [a,b]. Input The input contains several test cases.…
