Luogp1962 Fibonacci series, P1962 Fibonacci SeriesBackground As we all know, the Fibonacci series is a series that meets the following characteristics: • F (1) = 1 • F (2) = 1 • F (n) = f (n-1) + f (n-2) (n ≥ 2 and n is an integer)Description Find the value of f (n) mod 1000000007.Input/Output Format Input Format: · Row 1st: an integer n Output Format: Row 3:

First: Using a For loopThe use of the For loop, does not involve functions, but this method for my small white is a good understanding of the function of a more abstract ...1 >>> fibs = [0,1]2 for in range (8):3 Fibs.append (Fibs[-2] + fibs[-1])45 >>> fibs6 [0, 1, 1, 2 , 3, 5, 8, 13, 21, 34]Or, enter a dynamic length:1fibs = [0,1]2num = input ('howmany Fibonacci numbers does you want?

Question Link Give N and M, and find F (n) % m. f (x) is the Fibonacci sequence. Idea: Because N is big, it is very likely that it will use the formula to calculate it, so we can use the Matrix to quickly solve the power. | (1, 1), (1, 0) | * | f (n-1), F (n-2) | = | f (N), F (n-1) |, so f (N) equivalent to | F (1), F (0) | multiplied by N-1 | (1, 1), (1, 0) |. Code: #include Uva10299-modular Fibonacci

Logu P1306 Fibonacci common count, p1306 FibonacciDescription You should be familiar with the series of Fibonacci:, 13 ~~~ But now there is a very simple question: what is the maximum number of public appointments between the n and m items?Input/Output Format Input Format: Two positive integers n and m. (N, m Note: The data is large. Output Format: The maximum number of common Fn and Fm. Since reading b

The meaning is to use matrix multiplication to find the last four digits of the nth of the Fibonacci series. If the last four digits are all 0, the output is 0. Otherwise Remove the leading 0 from the last four digits of the output... ... Yes... ... Output FN % 10000. The question is so clear .. I am still trying to find the last four digits of % and/and determine whether all the values are 0 and whether the output values are 0. Remove the leading 0.

Calculate the nth entry of a Fibonacci series. The upper limit of n is 10000. Solution: Because the upper limit of this question is 10000, indentation is required for high precision. # Include

Question: Fibonacci series, F [0] = 0, F [1] = 1, F [N] = f [N-2] + F [n-1], n> 1 Given N (0 Solution: N is too large, so we cannot use the cyclic recursive Calculation of O (n ). Conclusion: For matrices | 1 1 |, and matrices | FnFn-1 |, after the two are multiplied to obtain a new matrix | Fn + 1FN|, FN indicates the nth Number of fiber ACCI | 1 0 || Fn-1 Fn-2 || FnFn-1 Therefore, we can use the rapid power modulo + matrix multiplication of O (l
