Implementing the Fibonacci (Fibonacci) function with Python

the following principle (requires a bit of linear algebra knowledge):First look at the previous iteration version of the Fibonacci function, it is easy to find that there is a transformation: y->x, X+y->y. A different angle is [x,y]->[y,x+y].Here, I declare a two-dollar vector [x,y]t, which is obtained by a transform [y,x+y]t, which can easily get the transformation matrix is [[1,0],[1,1]], that is to say:

Data structure (ix) Order lookup for lookup tables, binary lookups, interpolation lookups, and Fibonacci lookups

, key=6 at the moment. (5), by 82>58 This result we can know that the first half of the previous round of the lookup table should be discarded. We narrowed the lookup table to the second half (section F (4)). The second half of the number of elements is f (4) = 3, we can continue to split the lookup table, the moment the key=4. We first update the position of the low, low=mid+1=5+1 = 6. Then mid = Low+f (3)-1 = 6+2-1=7. At this moment 82=items[m

Use the Fibonacci (Fibonacci) sequence to solve ZZ

Describes the natural laws of the number of animals that breed and the change of plant bits. As a typical mathematical problem, the Fibonacci series are often used as examples in programming, data structures, algorithms, and other related disciplines. The following is a simple analysis of the common algorithm for solving the Fibonacci series. 1. recursion. In most textbooks, we always like to take the

HDU2516 Stone Game (Fibonacci game) __ The Fibonacci game

Problem Description 1 heaps of stones have N, two people take turns. The first person can take any number of the 1th time, but not all of them. The number of stones to be taken at a later time cannot exceed twice times of the last number of children. Take the winner. Negative output of the first SecondWin "first win" wins the output. Input There are multiple groups entered. The 1th line of each group is 2Output First take the negative output "Second win". First win is the output of the winner.

Project Euler 104:pandigital Fibonacci ends both ends of the full number Fibonacci number

Pandigital Fibonacci EndsThe Fibonacci sequence is defined by the recurrence relation: F[n] = f[n-1] + f[n-2], where f[1] = 1 and f[2] = 1. It turns out that F541, which contains 113 digits, was the first Fibonacci number for which the last nine digits was 1-9 PA Ndigital (contain all the digits 1 to 9, and not necessarily in order). And F2749, which

Python implements the Fibonacci sequence (Fibonacci sequence)

Using Python to implement the Fibonacci sequence (Fibonacci sequence)Fibonacci sequences are like 1,1,2,3,5,8,13, and so on. In other words, the next value is the sum of the first two values in the sequence. Write a function, given n, to return the nth Fibonacci number. For example, 1 returns 16 return 8I chose two met

"Binary search" and "Fibonacci Lookup" (Fibonacci search)

First, let's look at an author's my book, a two-point lookup code The return value is the subscript of key and returns -1template It can be proved that the time complexity of the algorithm is O (NLOGN), considering the preceding coefficients, is approximately o (1.5nlogn). However, there is still room for improvement in this implementation. Notice that the loop requires only 1 judgments to decide whether to go to the left, but 2 times to determine whether to go to the right. That is, in the lef
