I decided to create a website with Codeforces & USACO problems divided by topic and difficulty.

I started by taking one problem, 893C - Rumor, and creating a video tutorial explaining Depth-First Search(DFS) and the solution to the problem. At the end of the video, I wrote the C++ code without complex syntax and I explained the code, line-by-line, as I wrote it.

I think that explaining the code for the solution will help a lot of people implement the solution.

I know that many people know DFS, but there are many people who don't know DFS who this tutorial will benefit.

Here is the video: https://www.vplanetcoding.com/course-2-standard-algorithms-and-data-structures#1
