Explanation:
import java.util.Scanner;
public class LabProgram{
public static int fibonacci(int n) {
/* Type your code here. */
if(n<0)
return -1;
if(n==0||n==1)
return n;
else
return fibonacci(n-1)+fibonacci(n-2);
}
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int startNum;
System.out.println("Enter your number: ");
startNum = scnr.nextInt();
System.out.println("fibonnaci(" + startNum + ") is " + fibonacci(startNum));
}
}
Recursions involve calling a function from the function itself, until a condition is met.
The required function, where comments are used to explain each line is as follows:
//This defines the function
public static int fibonacci(int n) {
//The function returns -1, if n is negative
if(n<0){
return -1;}
//The function returns the value of n, if n is 0 or 1
if(n==0||n==1){
return n;}
//If otherwise
else{
//The function returns the nth term of the Fibonacci series
return fibonacci(n-1)+fibonacci(n-2);
}
}
At the end of the program, the nth term of the Fibonacci series is printed.
