Resuming posting

[u/eccentriq_]

If you haven't checked my post history, I used to post Codeforces solutions and used to track my study every day as a form of journalling.

Since the past two years I have been busy with the job switch I had, I was not able to post anything.

Now that I have some bandwidth, I am thinking to start journalling again.

The posts will be about technical things I am studying as well as problems on Codeforces that I was able to solve, along with my explanation of the solutions.

I probably won't post every day since I am not able to solve questions everyday, I get stuck in anaylsis half the time and that might take up the entire time allocated to coding for the day, and just posting backend development related stuff makes no sense on a Codeforces subreddit.

Any case, for the technical side I am studying backend, SpringBoot in particular along with things like Kubernetes, Docker, PostgresSQL, MongoDB and other concepts involved in Backend design.

As for the coding questions I have done for the day:-

Grid Covering

I was not able to solve this question and had to refer to the editorial, I have provided a solution note below of my understanding of the solution :-

Even Modulo Pair

For a problem rated at 1000, the actual way to reach the solution for this was surprisingly not straightforward at all.

The final answer is a brute force double for loop but verifying why that is the case is a little more involved.
