Question

#Remember that Fibonacci's sequence is a sequence of numbers

#where every number is the sum of the previous two numbers.

#

#Joynernacci numbers are similar to Fibonacci numbers, but

#with two differences:

#

# - Fibonacci numbers are famous, Joynernacci numbers are

# not (yet).

# - In Joynernacci numbers, even-indexed numbers are the

# sum of the previous two numbers, while odd-indexed

# numbers are the absolute value of the difference

# between the previous two numbers.

#

#For example: the Joynernacci sequence starts with 1 and 1

#as the numbers at index 1 and 2. 3 is an odd index, so

#the third number would be 0 (1 - 1 = 0). 4 is an even

#index, so the fourth number would be 1 (0 + 1). 5 is an

#odd index, so the fifth number would be 1 (1 - 0). And

#so on.

#

#The first several Joynernacci numbers (and their indices)

#are thus:

#

# 1 1 0 1 1 2 1 3 2 5 3 8 5 13 8 21 13 34 21

# 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

#

#Write a function called joynernacci that returns the nth

#Joynernacci number. For example:

#

# joynernacci(5) -> 1

# joynernacci(12) -> 8

#

#We recommend implementing joynernacci recursively, but it

#is not required.


#Write your code here!


#Below are some lines of code that will test your function.

#You can change the value of the variable(s) to test your

#function with different inputs.

#

#If your function works correctly, this will originally

#print: 1, then 8

print(joynernacci(5))

print(joynernacci(12))
