This is why I thought that maybe using ArrayList would give me access to use List methods too along with the ones from ArrayList. After reading your suggestions, I looked at the comments below the answer and realized that List is an interface and it's methods are basically ArrayList methods for both cases. I feel now the answer was somewhat misleading. Thanks for all your pointers. Also, the constraint says about range of N: `0 < N < 10 ^10`. That's why i used long.

But I did read up on Lists vs ArrayLists before writing my solution, and according to the answer on this SO problem, it says- When you define your list as: `List myList = new ArrayList();` you can only call methods and reference members that belong to List class. If you define it as: `ArrayList myList = new ArrayList();`
