Hello @ann8497 !
This is a traditional example of game theory . You just need to think of corner cases .
So , basically for every n you have to insert grundy of every divisors of n including 1 but not n itself in a set .And then return Mex of the elements of set .
if you still have confusion , you can go through this code -->
