The diagram above shows a tiling of 7 squares with \(A\) and \(B\) denoting the initial point and destination point respectively. The arrow signs indicate the direction that you're able to travel to (east, south, north-east). Find the total number of ways to reach point \(B\) from point \(A\).
Bonus: Generalize this for \(n\) squares.
