Tip 1 : Competitive programming plays a major role when you are appearing for coding rounds as a fresher. In the coding rounds, you won't get direct problems copied from the internet. You would be required to use your logical thinking to go ahead in the process. This is where competitive programming helps.
Tip 2 : Coding rounds are all about Coding + Timing. Most people fail to excel due to the pressure of a timer ticking on their heads. So, instead of just solving problems, try to participate in timed contests. This will help you be used to the pressure of the timer.
Tip 3 : Many big companies expect you to be good at standard problems. So, once you are done with the coding round by your logical skills and competitive programming, you must be well versed with some standard problems in order to excel.
Tip 1 : Make it short, crisp, and simple. It is always good to have a 1 pager resume.

The data you store in a NoSQL database does not need a predefined schema like you do for a SQL database.

Mark the position output[i][j] as 1 and check if the current position is destination or not. If destination is reached print the output matrix and return.
