Introduction
Welcome, this gitbook is my personal archive of writeups / contest record / answers which I had participated / taken / practiced from various contests.
Overview
Most of the solution will be given by my personal explanation, if possible, most of the answers are validated to pass all test cases, unless specifically mentioned.
Note that most of the solutions are written in Python. If you guys want the other language, you may just call GPT / coding AI etc to translate it, but I highly recommend you try it yourself instead.
This gitbook aims to serve as a study resource for students / amateurs / passerby who is interested on competitive programming (CP) preparing and familiarize the actual challenge.
If you are really good at competitive programming, feel free to point out any optimization / hints / criticize my solutions, and I will be grateful to consider the insightful comments.
