Answer 1

Answer:

def fib(n):

   if(n==1):

       return 1

   elif(n==2):

       return 1

   else:

       return fib(n-1)+fib(n-2)

   

try:

   n=int(input())

   e=0

   o=0

   if(5<n<=20):

       for i in range (1,n+1):

           x=fib(i)

           print(x,end=' ')

           if(x%2==0):

               e+=1

           else:

               o+=1

       print()

       print(e)

       print(o)

   else:

       print("INVALID INPUT")

except:

   print("INVALID INPUT")
