Greetings Codechef Community.
This is my first blog on Codechef. This month’s long challenge was really good for me, I secured Indian rank 1 and global rank 6. Most of the hard problems require Advanced data structures such as Persistent Segment Tree , Centroid Decomposition. There are very few blogs and problems on these topics. That’s why Me and my friends Anshu Garg (run_timeterror), Sharabh Agarwal (Catastrophic25) prepared an unofficial editorial where I share my ideas on how I solved these problems. I also attached the links from where I learned these topics.
