If you are facing problems solving this , now you can come here for the solution. So after taking the necessary input, you begin from the first index (currentIndex - set to 1). Then you enter a while loop. Here on every iteration you check whether you've reached your destination, on which case done variable will be true. If currentIndex > destination, you'll never get to destination since you can't travel backwards. In this case you just break out of the loop. The loop will terminate once you've traversed the whole array.

Finally you check  whether done is true (you've reached your destination) or false(otherwise).
