Can i have solution for this problem , with explanation

#1

For this tilling2 problem

#2

Recursive function for this problem should be something like this:
int noofways(int n,int m)
{
if(n==0)
return 1;
if(n<0)
return 0;

int way1=noofways(n-1,m);
int way2=noofways(n-m,m);
return (way1+way2)%1000000007;
}

However just by recursion, your code will not pass all the test cases and will give Time Limit Exceed error since the constraints are large. You need dynamic programming to solve this problem. So i would suggest you to attempt this problem after completing Dynamic Programming concepts.
