Solution
To find the Nth Fibonacci number, we can use a recursive approach.
First, we need to take an input integer N, which represents the position of the Fibonacci number we want to find.
Next, we can define a recursive function that takes an integer parameter N and returns the Nth Fibonacci number.
Inside the function, we can check if N is either 0 or 1. If it is, we can simply return N as the Fibonacci number at that position.
If N is greater than 1, we can recursively call the function with N-1 and N-2 as parameters, and add the results together to get the Nth Fibonacci number.
Finally, we can call the function with the given input N and print the result as the output.
Here is an example implementation in C:
#include <stdio.h>
int fibonacci(int n) {
if (n == 0 || n == 1) {
return n;
}
return fibonacci(n-1) + fibonacci(n-2);
}
int main() {
int N;
scanf("%d", &N);
int result = fibonacci(N);
printf("%d\n", result);
return 0;
}
This code takes an integer input N, calls the fibonacci function with N as the parameter, and prints the result.
