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.
Algorithm ListIn this paper, the optimal algorithm is found from the perspective of time efficiency and occupied space memory.
Classic recursive algorithm recursive algorithm (very slow)
Dynamic storage algorithm programming (slow)
Matrix Power algorithm exponentiation (FAST)
Multiple formula algorithm fast doubling (soon)

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
Original question: Chess is a Two-player board game believed to has been played in India as early as the sixth century. However, in this problem we won't discuss about chess, rather we'll talk about a modified form of the classic N-quee NS problem. I know you is familiar with plotting n-queens in a chess board with the help of a classic backtracking algorithm. If you write that algorithmNow you'll find that there is ways of plotting 8 queens in a 8x8 board provided no Queens attack each other. I
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

Recently playing Python, after a cursory look at learning python and core python, I stumbled upon a post on the web. The evolution of Python programmers is interesting. So I intend to imitate an article, that post used more than 10 ways to complete a factorial function, I will write a

Python development [algorithm]: time complexity of the Fibonacci series, python FibonacciFibonacci Series
Overview:
The Fibonacci series, also known as the Golden split series, refers to a series of 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 ,...... In mathematics, the Fibonacci sequence is defined as follows in a recursive method: F (0) = 0, F (1) = 1, F (n) = F (n-1) + F
In fact, the Fibonacci sequence of things I have learned in elementary school, but only then did not learn so clearly, now let us take a look at the Fibonacci sequence of some algorithms (beginners can see)Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ... [1]If you set F (n) to be the nth item of the series (n∈n*), then this sentence can be writ
Soon Blue Bridge Cup match, I these algorithms still not, indeed a bit of panic, today morning to sleep late not to get up, then began to study the 8 queen question. This is also a typical backtracking and recursion problem. In fact, and horse tread board problem very similar, eight Queen question, is to judge the main diagonal, diagonal, horizontal and vertical row can not have

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

Description
A Fibonacci sequence is calculated by adding the previous two membersOf the sequence, with the first two members being both 1.
F (1) = 1, F (2) = 1, F (n> 2) = f (n-1) + f (n-2)
