The parent function is also called the generating function. The definition is given sequence: A0,A1,A2,....... ak,......, then function g (x) =a0+a1*x+a2*x2+......ak*xk is called sequence A0,A1,A2,....... AK,...... The parent function (that is, the build function).
For example, the generating function for sequence 1,2,3.......N is: G (x) =x+2x2+3x3+........nxn. Click this link: Baidu Encyclopedia

Fibonacci sequence (Fibonacci), except for the first and second numbers, can be summed up by the top two numbers:1, 1, 2, 3, 5, 8, 13, 21, 34, ...The Fibonacci sequence is not written in a list, but it is easy to print it out with a function:>>>deffib (max): N,a,b= 0,0,1 whilenMax:Print(b) a B=b,a+B N=n+1return ' Done'>>> FIB (10)11235813213455' Done'" "looking closely, it can be seen that the FIB function

Because it is often used in the description of complex algorithms, we will discuss it before introducing other algorithm design methods.Algorithms that can use recursive descriptions usually have the following features: To solve the N-scale problem, we try to break it down into smaller-scale problems, then

F [0] = a ^ 1 * B ^ 0% P, F [1] = a ^ 0 * B ^ 1% P, f [2] = a ^ 1 * B ^ 1% p ..... f [N] = a ^ fib [n-1] * B ^ fib [N-2] % P.
Here, P is a prime number and a and P are mutually Prime, So we calculate a ^ B % P. When B is very large, we need to reduce the power of B.
Because a and P are mutually unique, a ^ (p-1) % P = 1 is known by the Fermat theorem. M
Fibonacci series:
Set F (n) to the nth (n, n +) of the series ). This statement can be written as follows:
F (0) = 0, F (1) = F (2) = 1, F (n) = F (n-1) + F (n-2) (n ≥ 3)
From the first item, each item is the sum of the first two items. Obviously, this is a linear recursive series.
For more information about this series, see: http://baike.baidu.com/view/816.htm

The rabbit problem, the number of steps on the stairs, is a series of Fibonacci.
Fibonacci can be simply implemented using recursion:
