Fibonacci number series code example

Example 1: fibonacci sequence

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...

Example 2: Fibonacci series

//to find nth fibonacci number(recursive solution)
class Solution {
    public int fib(int n) {
     if(n==0){
         return 0;
     }
        if(n==1){
            return 1;
        }
        if(n==2){
            return 1;
        }
        return fib(n-1)+fib(n-2);
    }
}

Example 3: fibanachi

function fib(n){
	var fib = [0, 1];
	var i = 0;
	for (let i = 0; i != n-2; i++){

		fib.push(fib[i]+fib[i+1]);

	}

	return fib;

}
