Hello everyone. Here is my "analysis" on today's 550 problem from TopCoder SRM 648 (Div. 1).

This was a pretty hard problem for me. I was unable to solve it :(. After the contest, I tried to understand the Accepted solutions. After this, I wrote this analysis to (hopefully) "recreate" and recapture the ideas necessary to solve the problem on my own.

I hope this helps!

Hello,

Here is one of my in-depth problem analyses for the recent SRM636 500 problem (ClosestRabbit).

As usual, please comment below if you have any suggestions / questions.

PS: The blog is going through some "renovations". I decided to move it away from the infamous WordPress. So some features/old-posts may be missing right now.

Cheers!

If anyone was wondering, here is my personal post about the 550 problem from yesterday's TopCoder round.

In summary, this problem required modular arithmetic and a trick I've seen used to solve the Coin Change Problem. Let me know if you have any comments or questions!

Here is a short editorial on TopCoder SRM 605 Medium problem, AlienAndSetDiv1. As mentioned, I would like to share more as I am learning. Maybe this will help me learn better and help others learn as well! Spoiler

I call it "Theory of Problem Solving": a blog of tutorials and in-depth analyses of the problems that I solve. I would like to share this with everyone in the Codeforces community!

It's just getting started, and many of my analyses are really long, because I wanted to focus on the process more than the solution. Anyway, take a look at the analysis of Codeforces Round #224 (Div. 2) E — Ksenia and Combinatorics!

Feel free to make comments or requests for specific problems!

Thanks everyone! Happy Coding! I will be posting more soon. Cheers!
