Pls I don't understand how this recursive function works. I mean the odd and even function. I can't get the logical view.

Answer 1

*** Indirect Recursion
(also called Mutual Recursion)

def function_1():
# <base case>
# call function_2

def function_2():
# <base case>
# call function_1

- Indirect Recursion is the implementation of recursion which requires 2 or more functions calling each other until a base case in any function is met (note that backtracking will happen).

- When any base case in function 1 or 2 is met, the recursion tracks back.

- Base case could be met either in function 1 or 2.

- Function 1 will try to reach the base case of function 2; while function 2 tries to reach the base case of function 1.

- If there's only 1 base case - in function 1 for example, the function 1 try to reach its base case through calling function 2, which is in turn trying to reach the base case of function 1.
