Hi Anish,

Sorry to be a stickler, but can you also post the question numbers? For ease-of-use, we want people to be able to search the forum by source and number.

Also, since these are OG problems, I assume you (and other forum users) have already read the OG solution. We might be able to give you a more specific explanation if you can also tell us where the OG solution lost you.

Thanks.
