I am solving spoj problem Tiling a Grid With
Dominoes.(http://www.spoj.pl/problems/GNY07H/)..
I am not able to come up with a recurrence relation..
One of my friend said it has the recurrence relation as f(n) = f(n-1)
+ 5*f(n-2) + f(n-3) - f(n-4).
I am not convinced and have trouble deriving this
well i have used three recurrences :P formed them by following a
traditional approach
f[i] = f[i-1] + 2*g[i-1] + h[i-1] + f[i-2];
g[i] = f[i-1] + g[i-1];
h[i] = f[i-1] + h[i-2];
