You're almost at Diagon Alley to buy your school supplies. How thrilling! Well, there's only one thing standing in your way,
quite literally, a wall. You know this wall is somehow the gate to Diagon Alley. You remember overhearing someone with a pointy
hat saying something along the lines of:
"Start at brick 3.7, Go three bricks left upwards, three bricks right, two bricks left down, two bricks right down and three bricks left down".
What brick do you need to tap to enter Diagon Alley?
