Dropbox Phone Interview

I was asked LC 289. Was able to solve it completely and answered a few more questions on how to deal with cases where the board has many (say, a million) cells.

Ended up getting a reject as my code had initally failed due to silly errors which the interviewer helped me debug (I was able to get it to run in the end). I know this as the recruiter was nice enough to give me a call about a week later to let me know the results & the interviewer’s feedback.
