## Minimum count of numbers in the Fibonacci series

### Question:

To find the minimum count of numbers in the Fibonacci series and their sum is equal to the number **n.**

## Logic:

- Generate the Fibonacci series to find the count.
- Pass the series and
**n**to the function. - Find the nearest smaller Fibonacci number to
**n**and increment the count. - Then subtract the nearest number with
**n**and assign value to**n**. - And Recursively repeat the process until
**n**become zero.

## Program:

#include<stdio.h> int sum(int a[],int n) { static int c=0; //minimum no of count to reach the number n int i; for(i=0;i<30;i++) { if(a[i]>n) { printf("%d ",a[i-1]); n=n-a[i-1]; //a[i-1] is the nearest smaller number to n c++; //increment the count break; } } if(n==0) //return the count when number is zero return c; else sum(a,n); //call the function recursively } void main() { int a[100],i,count=0,n; printf("Enter the number:"); scanf("%d",&n); a[0]=0,a[1]=1; for(i=2;i<30;i++) //generates the Fibonacci series { a[i]=a[i-1]+a[i-2]; } count=sum(a,n); //Pass the value and array to find the minimum count printf("Count: %d",count); }
