TLE in Tiling Problem 2

#1

I tried using recursion method like in the example of 4xN. I used MOD value and long long but still it is giving TLE. I solved it without recursion.
Is it possible to solve this using recursion given the constraints and not get TLE?

hello @brucewayne
no we cant solve it with only recursion.

we need dynamic programming for its optimisation
