Question 6
Pierre the beaver lives on island 1 in the picture below. He receives the code “B – A – C – A – A – B”. The code tells him which bridges to cross to reach the hidden treasure.
However, some instructions may not match any bridge available at his current island. Pierre simply skips those instructions. For example, if the instructions are A – B – A and Pierre starts on island 1, he first goes to island 2. Then, since no bridge B is available, he skips that instruction and follows the next instruction by crossing bridge A back to island 1.
On which island will Pierre find the treasure by following his code?
