fibonacci series i code example

Example 1: fibinachi

def fib(n):
  lisp = []
  
  for i in range(n):
    if len(lisp) < 3:
      if len(lisp) == 0:
        lisp.append(0)
      else:
        lisp.append(1)
    
    else:
      lisp.append(lisp[len(lisp)-1]+lisp[len(lisp)-2])
  
  return lisp

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);
    }
}
