Space 512M time 2s"Title description"There are n positive integers greater than 1 a1,a2,..., an, we know that the recursion of the Fibonacci sequence is F (i) =f (i-1) +f (i-2), Now we modify this recursive to F (i) =f (i-1) +f (i-2) +r (i-1), where R (x) is a1,a2,..., an in x The number of approximate numbers. The value of the F (m) MoD 19940417 is now required . Note: initial value F (1) =1,f (2) =1Input

The 4-order Fibonacci sequence is as follows: F0=f1=f2=0, F3=1,..., fi=fi-1+fi-2+fi-3+fi-4,Using a cyclic queue with k=4 capacity, the first n+1 items of the sequence (F0, F1, F2,... fn) are constructed, and fn≤200 fn+1 is required to be satisfied.#include #include #define MAXSIZE 4typedef struct {int *base;int front;int rear;int length;}sqqueue;sqqueue* Initqueu

What is the Fibonacci sequence?--a group of values starting from the third value, each equal to an interesting sequence of the sum of the first two valuessuch as [1, 1, 2, 3, 5, 8, 13, 21, 34, 55]How do I implement it with a program?--Logical finishingInitial value n_1 = 1, n_2 = 1N_3 = n_1 + n_2The third value starts with each value being the sum of the first tw

Defined: The Fibonacci sequence refers to such a sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...This sequence begins with the third item, each of which equals the sum of the first two. Take the first 20 items of the Fibonacci series as an example: Method One:A

Problem DescriptionThe recursive formula for the Fibonacci sequence is: Fn=fn-1+fn-2, wherein f1=f2=1.When n is large, FN is also very large, and now we want to know what the remainder of FN divided by 10007 is.Input FormatThe input contains an integer n. output FormatThe output line contains an integer that represents the remainder of FN divided by 10007. Note: In the subject, the answer is to require FN d
