# Easy fibonacci exercise
# Method #1
def fibonacci(n):
    # 1th: 0
    # 2th: 1
    # 3th: 1 ...
    if n == 1:
        return 0
    elif n == 2:
        return 1
    else:
        return fibonacci(n - 1) + fibonacci(n - 2)

# Method #2
def fibonacci2(n):
    if n == 0: return 0
    n1 = 1
    n2 = 1
    # (1, n - 2) because start by 1, 2, 3... not 0, 1, 1, 2, 3....
    for i in range(1, n - 2):
        n1 += n2
        n2 = n1 - n2
    return n1


print(fibonacci(13))
# return the nth element in the fibonacci sequence

fibonacci series

#fibonacci series is special type of sequence
#fibonacci series is somethinng liket this-->
#0,1,1,2,3,5,8,13,21,34,55,89.......
#addition of former two succesive number results in the third element.
#in simple way as given in above series that 0,1,1--> where 0+1=1 e,i; 1
#example: 2,3,5 addition of 2 and 3 results in latter element in sequence e,i 5
8,13,21 :  8 + 13=21
34,55,89:  34 + 55=89
