The Fibonacci sequence uses recursion to derive answers. It is defined as: F0 = 0
F1 = 1
Fn = F(n - 1) + F(n -2) To have this sequence printed by a php script use the following:
function fibonacci($n)
{
if($n 1)
return 1; //F1
else
return fibonacci($n - 1) + fibonacci($n - 2); //Fn
} This recursive function will print out the Fibonacci number for the integer n. To make it print out all the numbers in a particular set add this to your script.
for($i = 0; $i < 15; $i++)
{
echo fibonacci($i) . "<br />";
} So your final result would look like. <?php
function fibonacci($n)
{
if($n 1)
return 1;
else
return fibonacci($n - 1) + fibonacci($n - 2);
} for($i = 0; $i < 15; $i++)
{
echo fibonacci($i) . "<br />";
}
?>
Is this a homework question?
You mean you have written a program, but you don't understand it? Well, how could I explain it without seeing it?
public static int fib(int n) {return fib(n-1) + fib(n-2);}
In c: int fibr(int n) { // Find nth Fibonacci number using recursion. if (n<=2) return 1; // the first two Fibonacci numbers are 1 and 1 return (fibr(n-2)+fibr(n-1)); } int fibi(int n) { // Find nth Fibonacci number using iteration. int temp,last=1,f=1; int i; for (i=3;i<n;++i) { // the first two Fibonacci numbers are 1 and 1 temp=f; f+=last; last=temp; } return f; }
Here is a good answer for recursion Fibonacci series. #include <stdio.h> #include <conio.h> long Fibonacci(long n); int main() { long r, n,i; printf("Enter the value of n: "); scanf("%ld",&n); for(i=0;i<=n;i++) { printf(" Fibonacci(%ld)= %ld\n", i,Fibonacci(i)); } getch(); return 0; } long Fibonacci(long n) { if(n==0 n==1) return n; else { return (Fibonacci(n-1)+Fibonacci(n-2)); } } for n=5; Output: Fibonacci(0)=0 Fibonacci(1)=1 Fibonacci(2)=1 Fibonacci(3)=2 Fibonacci(4)=3 Fibonacci(5)=5
#include #include void main(void) { int i,j,k,n; clrscr(); i=0; j=1; printf("%d %d ",i,j); for(n=0;n<=5;n++) { k=i+j; i=j; j=k; printf("%d ",k); } getch(); }
Yes, this can be done. For example for Fibonacci series. You will find plenty of examples if you google for the types of series you need to be generated.
A recursive function is one in which the value of a function at each point depends on its value at one or more previous points. A rercursive function requires the first few values to be defined normally - these are called bases. Perhaps one of the most famous recursive function is the Fibonacci series, which has f(1) = 1 f(2) = 1 f(n) = f(n-1) + f(n-2) for n = 3, 4, 5, ... There are two bases and each subsequent value is defined in terms of the preceding two.
No. Grapes have nothing to do with a recursive series of numbers following the rule that any number is the sum of the previous two.
Exactly what do you mean by 'C program in Java'
I did this as an answre to some common js questions , the question wasWrite a function which will return you first two times 1, then 2, then 3, then 5 and so on (Fibonacci numbers). Don't use any global variables.var fibonacci = (function () {var arr = [0, 1];return function () {var num = arr[arr.length - 1],len = arr.length;arr.push(arr[len - 1] + arr[len - 2]);return num;};}());//testvar i;for (i = 0; i < 10; i++) {console.log(fibonacci());}//1,1,2,3,5,8,13,21,34,55

It is a function which returns itself.Whenever function is called from itself then there is a chance that the function will enter in to an infinite loop.To prevent the program from entering in to a infinite loop.To prevent a program from entering in to an infinite loop in such a manner,every recursive function must have terminating condition that decide whether to call the function once more or not.This terminating conditions is also known as stopping rule in recursive function.Using Recursion to Print the Fibonacci Series #include#includevoid main(){int c=1,f=0,s=1;int i;printf("%d%20d\n",f,f);printf("%d%20d\n",s,s);for (i=2; i
i dn't know. haha
#include#includevoid fibonacci(int x){int f=0,m=-1,n=1,i=0;while(i
20 is not a term in the Fibonacci series.
#include<stdio.h> #include<conio.h> void fibonacci(int x) { int f=0,m=-1,n=1,i; for(i=0;i<x;i++) { f=m+n; printf("%d\n",f); m=n; n=f; } } void main() { int n; clrscr(); printf("\nEnter the limit:"); scanf("%d",&n); fibonacci(n); getch(); }
Fibonacci!
