Hello Codeforces!
Today, after reflecting on the advice under my comments and putting them together, I learned one very good piece of advice that I will stick to moving forward. Today I finished the 1st thematic collection of problems, it was on the topic of arrays, maps, sets, etc. Again I tried to extract something useful from these problems, and began to notice that mostly brute force problems are often solved without much optimization (if I’m wrong, correct me). I need to do more to achieve the goal, because 1/4 of the way has already passed, and I have only reached 1100 rating (I lost it at the last competition :( ).
Plans for tomorrow:
Don't be lazy, try to finish the 2nd thematic collection of problems right away, prepare for the approaching Div1-2.
