The Fibonacci sequence was my exposure to math classes in junior high school, and the only thing that was interested in that was his name, because he had been thinking about who had a so awkward name ...

Series 1, 1, 2, 3, 5, 8, 13, 21, 34, ... Called the Fibonacci sequence. This sequence has a lot of magical properties, one of which is that the square of each Fibonacci number is exactly 1 compared to the product of the two Fibonacci number before and after it. Specifically,
For the Fibonacci sequence, 1,1,2,3,5,8,12,... To solve the nth value, we usually use a recursive algorithm, that is, a recursive f (n) = f (n-1) +f (n-2). However, this is a very inefficient algorithm, when n reaches 41, it has to need about 1s, with the increase of N, time is the number of levels of growth.Because the recursive algorithm has too many repeated calculations, as shown in the time t (n) = t (
The Fibonacci sequence is a very interesting sequence, starting with 0 and 1, after which the Fibonacci Fibonacci coefficients are added by the previous two numbers. The Fibonacci sequence

Question: Find the nth number in the Fibonacci sequence.
The so-called Fibonacci sequence refers to: The first 2 numbers are 0 and 1. The number of i-1 and the number of i-2.
The first 10 numbers of the Fibonacci series are:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34 ...
Answer:
(i)
We write the series:
fibonacci[0] = 0,fibonacci[1] = 1
Fibonacci[n] = fibonacci[n-1] + fibonacci[n-2] (n >= 2)
it can be written in the form of matrix multiplication:
The right continuous expansion will be:
The following is the calculation of an O (log (n)) algorithm:

Fibonacci series (Fibonacci sequence), also known as the Golden Section series, because the mathematician Leonardo's Fibonacci (Leonardoda Fibonacci) to the rabbit breeding as an example of the introduction, so called "Rabbit series", refers to such a series: 1, 1, 2, 3, 5,
Faipot Series (Italian: Successione di Fibonacci), also translated into Faipot , Fibonacci series , Fermi series , the Golden section of the series .
Mathematically, the faipot sequence is defined in a recursive way:
{\displaystyle f_{0}=0}
{\displaystyle F_{1}=1}
{\displaystyle f_{n}=f_{n-1}+f_{n-2}} (N≧2)
