• Now that Untrodden 2020 is over, I will resume AtCoder and Competitive Programming.

  • Since I don’t remember much, I’ll start by solving some ABC problems.

  • I should review algorithms and my own library.

    • I wonder if I should also include the AtCoder official library.
  • So, I’ll participate in today’s ABC contest on 3/13 for now.

  • Things I forgot:

    • Range of numerical types.
    • Various algorithms.
    • Computational complexity.
  • I realized that when I was participating before, I had adapted to the inconvenience of C++.

    • I had learned solutions to various difficulties and was able to write code smoothly.
    • I thought it would be different to try to remember that again.
  • My competitive programming skills have deteriorated significantly.

    • I even struggled with problem B.
    • Surprising.
    • Well, it seems like I just need to regain my sense of it.
